My EZ Battery Reconditioning Method Review

Highly Recommended

Of all books related to the topic, I love reading this e-book because of its well-planned flow of content. Even a beginner like me can easily gain huge amount of knowledge in a short period.

Overall my first impression of this ebook is good. I think it was sincerely written and looks to be very helpful.

Rechargeable batteries nonrechargeable batteries or AC adapters what is the best power supply for me

The more photos you take, the faster battery power is used up. Therefore, if you love to take photos often, you should consider buying a battery charger and rechargeable batteries. Many Olympus cameras are supplied with a high performance lithium-ion rechargeable battery and custom charger. For models using regular batteries, the Olympus Ni-MH (Nickel-Metal Hydride) rechargeable batteries are highly recommended. These environmentally-friendly, cadmium-free batteries have a long life and are ideal for the busy photographer. When it comes to selecting the charger, it pays to choose one with a battery protection system to help extend the batteries' life span. It is also a good idea to buy an extra set of batteries so you can carry on shooting while the other set charges. Some of the more professional-orientated digital SLR models allow the attachment of a battery pack. This rechargeable system supplies power for marathon shootings, so they are particularly suited for professional...

Tip Get Rechargeable Batteries Fast

Okay, your camera didn't ship with rechargeable batteries, which probably means that it's powered by 2 or 4 AA-type batteries. The set of lithium batteries the manufacturer bundled with the camera will work well, but they'll last only a few hours and are expensive to replace. For the price of a few sets of lithium AAs (never, ever buy alkaline batteries for your digital camera, because they'll last only 15-20 minutes before pooping out), buy a set of rechargeable nickel-metal hydride (NiMH) AAs and matching charger. NiMH batteries can be recharged hundreds of times, so you'll be paying pennies and not dollars for power every time you use your digital camera.

Choose the Best Battery Charger

Many newer digital cameras now come with their own battery chargers. If your camera uses AA batteries, it probably doesn't include a charger. When buying a battery charger, you should always pay a little extra to get a rapid charger as opposed to the regular chargers that can take an average of 13-15 hours to charge a battery. If you are going to be traveling by car (yours or a rental), consider buying a power inverter. These marvelous yet inexpensive devices, like the one shown in Figure 2-5, plug into the cigarette lighter of a vehicle and provide AC power, allowing you to plug your battery charger into it and charge your batteries while you're driving.

Battery Charging and Battery Life

All digital SLRs use one or more batteries of some type to provide power for the camera's various functions. One of these will be the main battery, usually a rechargeable nickel metal hydride (NiMH or lithium ion (Li-Ion power pack that can be removed from the camera for recharging or replacement. The dSLR might also operate using standard AA batteries (alkalines or rechargeables , non-rechargeable lithium cells, or an AC adapter that can be helpful when using the camera for long periods, such as in the studio or when shooting time-lapse sequences that can last hours or days.

Types of Rechargeable Batteries

NiCad (Nickel Cadmium) batteries are the most widely used type of rechargeable battery. They charge quickly, last approximately 700 charge and discharge cycles, and perform well in low temperatures. However, they do have one major problem. If you charge a NiCad battery, use only part of the charge, then recharge it again, it doesn't take a full charge. This is due to what's called memory effects. The memory effect reduces the overall capacity and run time of the battery. (NiMH-Nickel Metal Hydride and LiOn-Lithium Ion don't have this problem.) Over time, the stored charge gets smaller and smaller and the battery fails more quickly when used. For instance, if you repeatedly recharge a 2 hour NiCad battery after using it for 30 minutes, it will develop a memory that limits the battery's run time to 30 minutes. Memory effect is caused by gas bubbles accumulating on the battery's cell plates, reducing the area available to charge. To fix the battery and remove the gas bubbles, you need to...

Rechargeable Batteries

Rechargeable batteries lose a little life every time you charge them. Most rechargeables last for about 1,000 charges, after which they stop holding a meaningful charge and you need to throw them away. You can extend the life of these batteries by recharging them only when they're actually run down topping them off is like a regular recharge in that it heats the chemicals in the battery casing, which slowly reduces the battery's life. Leave the camera on If you're taking a lot of pictures in a brief time, don't turn the camera off after each and every picture. You might think that you're conserving battery life, but in fact you're burning energy every time the camera has to power on. That's especially true if your camera has to retract the zoom lens every time it powers down and extend the lens when you turn it on again. Use AC power when it's available When you're transferring images to the PC, don't rely on battery power. You should have an AC adapter to power the camera when you're...

Battery Power

To be honest, there's a lot to be said for good old AA batteries because they're cheap, you can take a stash with you, and they're available all over the world. Lithiums are also ideal for travel because they last longer and deal with low temperatures much better than alkaline batteries.

Battery Packs

I would strongly recommend acquiring a battery pack of some kind for your flashgun. Battery packs help you to achieve more consistent exposures by providing a faster recycling time for your flashgun. This allows you to shoot faster than if you were relying on the recycling power of AA batteries alone. With my Nikons, I use the Nikon SD-9 battery pack with my Canons, I use the Canon CP-E4 battery pack. I use NiMH rechargeable batteries with both of these battery packs. These packs can be clipped to your camera strap, so you're not tethered to a pack clipped to your belt (as with the high-capacity battery packs we'll look at in a moment). If a flash bracket is used, the battery pack can be screwed onto the onto the vertical pillar of the flash bracket. This gives you more flexibility in being able to switch your camera from shoulder to shoulder, or even to set it down if you need to. If I want more juice, or need to fire the strobe faster than those battery packs allow, there are...

O Battery Power

Since you don't need motorized film transport, there is no motor drive or winder on DSLRs, but the cameras still look the same because the manufacturers have smartly designed the auxiliary battery packs to look just like a motor or winder attachment. While most of these cameras run on AA-size batteries, it is advisable to purchase the auxiliary battery packs, since most digital camera systems (especially those with CCD sensors) chew up AAs like jelly beans. Most of the auxiliary battery packs used on DSLRs employ rechargeable Lithium-ion batteries.

Putting Batteries in the Camera

The camera's clock-calendar is powered by a separate rechargeable battery. When you put batteries in your camera for the first time or after a long period of storage, wait a few hours for the clock battery to recharge before removing the main batteries. cm Low battery O, Extending battery life While alkaline batteries are suitable for use in the COOLPIX 990, battery life can be extended by using high-capacity lithium or nickel-metal hydride (Ni-MH) batteries. The following techniques can be used to extend battery life Turn the LCD monitor off whenever possible (see right). Turning the monitor off eliminates the single biggest draw on battery power.

The Digital Rebel supports the industry standard PictBridge so you can connect the camera to photo printers and other PictBridge devices and print images without a computer. With Canon's CP-300 4 x 6 photo printer and a battery pack you don't even need an AC power connection.

Image Resolution and Memory Capacity

It's impossible to overstate how glorious it is to have a huge memory card in your camera (or several smaller ones in your camera bag). Since you're not constantly worrying about running out of space on your memory card, you can shoot more freely, increasing your chances of getting great pictures. You can go on longer trips without dragging a laptop along, too, because you don't have to run back to your hotel room every three hours to offload your latest pictures. Your camera's battery life is more than enough to worry about The last thing you need is another chronic headache in the form of your memory card. Bite the bullet and buy a bigger one.

Kodak Named In Top 20 List

Camera provides a wide range of picture taking including intelligent image recognition and viewing programs including slide show and beautiful flesh. A dedicated Li-ion battery pack (D-Li 108) powers the camera to take about 210 pictures on a charge. The camera measures 92 x 56 x 225mm, and weighs 127g (card and battery). The Optio 1500 will hit the shelves of local dealers on April 14th.

Additional Canon System Components

For lighting on the go, Canon offers the 580EX II, 430EX, and 220EX Speedlites. The ST-E2 transmitter allows control of slave flashes for up to 33 feet outdoors and almost 50 feet indoors. Macro photographers can benefit from the Macro Twin Lite MT-24EX or the Macro Ring Lite MR-14EX. In addition, you can add a variety of battery packs and magazines, hot-shoe adapters, TTL (through-the-lens) distributors, and off-camera shoe cords. A body, lens, and flash made a complete system for this wedding photographer, with great results (see 1-3).

So is it time to upgrade

In the early days of digital photography, it wasn't uncommon for a camera to run for a meager 20 minutes or so before battery power was depleted. Thankfully, you can expect significantly longer battery life now than in years past. Battery technology has advanced, and cameras have gotten better in terms of power management. Some cameras run on standard AA or AAA batteries, while others use a proprietary rechargeable battery designed for use just with the camera. The nice thing about AA or AAA batteries is that you can find those batteries virtually anywhere in the world the bad thing is that it gets costly to replace them all the time. You can save money by investing in rechargeables, but first make sure that your camera can work with them some older models can't. As for battery technology, common rechargeable battery types are Li-ion (lithium ion), NiCd (nickel cadmium), and NiMH (nickel metal hydride). NiMH is the best choice for AAs and AAAs most proprietary batteries are Li-ion....

Buy Plenty of Batteries

Figure 2-4 The rechargeable battery's capacity is displayed on the battery itself. Figure 2-4 The rechargeable battery's capacity is displayed on the battery itself. If your camera uses AA size batteries, you need to invest in at least two sets of rechargeable batteries so that you have one set in the camera while the other set is recharging. Radio Shack is a great place to purchase such batteries. Look carefully at the label on the pack of batteries for the battery capacity, listed in milleampere hours (mAH). The battery with the largest mAH value will hold the greatest amount of charge, which translates into more time between charges. The capacity range of an AA battery is typically from 1100-2200 mAH. The battery shown in Figure 2-4 is a pretty large capacity battery at 2000 mAH. Most of the newest digital cameras use a proprietary high-capacity Lithium Ion (Li-Ion) battery. The Li-Ion battery is much lighter than rechargeable AA batteries and holds a comparatively greater charge....

Recommendation Get Extra Batteries

You'll want an extra battery pack or a set of batteries to prevent frustration caused by loss of power. Check the price of this accessory. The rechargeable Ni-MH AA batteries are quite affordable, but some of the proprietary battery packs are very expensive. If you shoot a great deal and will often need to change batteries, you'll probably want a camera that accepts rechargeable NiMH AA batteries. Buy several packs. In a pinch, you may also be able to use universally available alkaline AAs, although they may not last for many shots, especially when using the camera's LCD monitor for framing your images.

Understanding How Lenses Work

You can get a top-quality lens and still save some money if you know how to interpret digital camera specifications. Many vendors share lenses and sensors among similar models in their product lines. I tested two cameras from the same manufacturer that had identical resolution and lens specifications, but one model was more compact, was outfitted with a rechargeable battery, and included rubber gaskets that made it water resistant. (It also cost more than 100 more ) A penny-pinching photographer who didn't mind a tiny bit more bulk, was willing to use AA batteries, and didn't plan any photography in rain showers could buy the less expensive version and save enough money to buy some extra memory cards or other accessories.

Noise comes from many sources

Photographers should avoid placing external battery packs close to their digital cameras. Some of these packs contain transformers that raise voltage levels for faster flash recycling and emit electromagnetic interference at the same time. This can result in severe degradation of digital image quality with heavy banding effects. In such cases, the best work-around is to carry the battery pack on a belt or a photo vest while connecting it to the flash unit via a cable.

Steve Bloom Tells How He Worked In Freezing Temperatures To Get This Incredible Shot Of The Northern Lights

There is something frustratingly annoying about battery technology in cold climates Batteries just don't last very long, and knowing how long they do last is a quantity photographers would love to discover. What we do know is that it depends on the state of the battery - an old one won't last as long as a new one, and some makes will last longer than others. However, be warned battery life is very short in extreme cold and it is a big problem for all photographers.

First Use of Digital Cameras

Wire service photographers who worked for such agencies as the Associated Press, United Press International, and Reuters and a few larger newspapers were the first main users of digital cameras, starting in the early 1990s. These first digital cameras were bulky, had a slight delay on the shutter release button, and were slow in terms of consecutive bursts, or frames per second. They also suffered by comparison to today's cameras from poor image quality, minimal storage capacity, and poor battery life. They were mostly hybrid cameras that were the result of marrying electronic film bodies to digital backs and self-contained battery packs. Kodak was the leader in producing these cameras and developing the early digital camera technology. These first digital cameras were expensive, with costs almost three to seven times those of current cameras. Of course, at the time, they were the latest technology available, and the industry welcomed them.

External Storage Devices and Viewers

If you shoot lots of images away from your home or office, or travel for days or weeks at a time and don't want to drag along a laptop, you would be well advised to buy either a mobile storage unit or a CD DVD burner. It's cheaper than simply buying more memory cards, and it will provide a bit more security. What makes these devices particularly useful is that they don't require a computer, and some are battery-powered portables that you can take with you literally anywhere in the world (and probably the space station, too). A mobile storage unit is a sophisticated electronic gizmo, ranging in size from a cigarette pack to a paperback book, which combines a tiny, high-capacity hard drive, an LCD viewer panel, one or more memory card slots, and a rechargeable battery. Priced about 250 to 600 (though one pro model costs thousands), they go by a variety of different names, such as portable hard drive or hand-held viewer. Pros love them because they provide fast, high-capacity storage for...

Describe How To Control Time

(2) If your camera uses an electrically-controlled shutter, always carry a spare battery with you and if you are planning to shoot in below-freezing conditions, try to find a camera with a completely mechanical shutter. Some camera makers do provide an accessory battery pack with a long wire attached. This allows you to keep the batteries in a warm inside pocket and still provide power to the camera. It's a bit cumbersome, but it works.

What to took for in a photographic stave flash

An electronic flash unit without power is an expensive paperweight. With the exception of the portable studio lighting kits, which require electrical outlets, electronic flashes usually require AA batteries, although the smallest might take AAAs instead. Rechargeable batteries generally provide an inexpensive option, although they tend to recycle (recharge the flash unit) more slowly than alkaline batteries do. PC cables and manufacturer flash cords malfunction (take care not to crimp them), so for important trips, carry extras (especially if you're going overseas, where it might be hard to find a replacement). Some rechargeable batteries also tend to lose their charge faster than alkaline batteries when stored.

Acquiring Other Useful Devices

Many of these items don't fall into any particular type of category, except that they do something useful. Some are quirky but cool, such as little shades that fasten onto the back of your camera and shield your LCD readout screen from the bright sun. Others are serious working tools, like the add-on battery packs described in an upcoming section. Photographers love gadgets, and you'll find lots of them for digital cameras. Here are a few of the most practical.

Battery Care in Cold Conditions

Batteries do not perform well in cold weather. At temperatures of 20 degrees F (-6.7 degrees C) or less, there is a danger that all battery-powered equipment will become sluggish. Outdoors in winter, your batteries give out in less than half the time they ordinarily last in more temperate conditions. Check the batteries for all your camera gear before going out into cold conditions and carry spares. Shutters are affected first, with shutter speeds slowing and producing exposure errors. For instance, if a battery-powered shutter is off by 1 1000 of a second, and if you are attempting to stop the action of a skier speeding downhill at 1 1000 of a second, then the exposure would be off by one f-stop. This would not present a serious problem unless you are shooting above 1 125 of a second. In cold conditions, make use of the middle and slow ranges of shutter speeds whenever possible to avoid this difficulty. When working in cold weather, carry a spare battery in an inside pocket, where...

What to look for in a photographic slave flash

An electronic flash unit without power is an expensive paperweight. With the exception of the portable studio lighting kits, which require electrical outlets, electronic flashes usually require AA batteries, although the smallest might take AAAs instead. Rechargeables generally provide an inexpensive option although they tend to recycle (recharge the flash unit) more slowly than alkaline batteries do. PC cables and manufacturer flash cords malfunction (take care not to crimp them), so for important trips, carry extras (especially if you're going overseas, where it might be hard to find a replacement). Some rechargeable batteries also tend to lose their charge faster than alkaline batteries when stored.

Why Does Minimalist Lighting Work So Well

We now have a new generation of electronic hot shoe flashes that can be used at full power or dialed down to 64 power or even J 128 power. New battery technology means these flashes run longer and recycle quicker than ever before. Rechargeable nickel metal hydride batteries (NiMH) can be reused for five hundred high-powered usage cycles and cost little more than disposable alkaline batteries.

Rechargeable Versus Alkaline

Unless you use your digital camera very infrequently, I recommend that you avoid alkaline batteries. Instead, invest in one or two sets of NiMH rechargeable batteries. Yes, they're initially more expensive. But they quickly pay for themselves, since you can use rechargeables over a hundred times on average. Do the math Let's say that you use your camera every weekend for a year, and you have to replace the batteries about once a month. Here's how the cost stacks up over the course of a year The more you use your camera, the more obvious the cost savings become. Once you've bought your first set of rechargeable batteries, additional sets are less expensive (usually under 10) because you don't have to buy another charger. So I think you can see how useful rechargeables actually are.

The Disappearance Of Certain Controls Has Made The Camera Less Intimidating

Finally, the new battery is significantly smaller and lighter than those Sony has used previously, weighing just 50g and slightly larger than a standard 9V battery. This may have come as a result of its reduced performance, though while the A350 could manage around 750 shots when using the viewfinder, the A380 is only quoted as having a 500-shot life. Using the viewfinder cuts this figure down to 230 shots (according to Sony), though these figures will vary from user to

The essential equipment for the landscape photographer

Batteries - Sometimes the best locations are also the most remote so make sure that you have plenty of batteries on hand to power your picture-taking exploits. Ensure that all rechargeable batteries are fully charged and that you have spares of any auxiliary batteries to use in the camera. Remember in cold weather batteries become less efficient so always carry spares of all power sources when things turn a little chilly. Good shoes - Now I am really sounding like your mother but good walking shoes are worth the investment if you plan to trudge through a tropical rainforest or climb over mossy rocks in search of the perfect photograph.

Battery and Memory Strategies

On any trip, you will need to manage two important resources power for the camera and memory cards (or film rolls). This task is obviously of utmost importance, as running out of either resource would mean no photography at all. Your goal should be to obtain not only continuous availability of both resources, but also the perception of continuous availability, for if you fear you will run out of memory or battery life, you will be pushed to shoot less. When it comes to selecting batteries and memory cards, weight and cost factors are of less importance than for other equipment. You should always feel secure that you will be able to shoot at any given moment. In other words, I would be happy to leave a lens that was too heavy for a trek, or take a cheaper DSLR body that still gave me adequate image quality, but I could never justify bringing too few batteries to save weight or money a battery charge, as well as how many images you shoot on an average day in the mountains and how much...

Batteries batteries batteries

It is possible to avoid switching your batteries until they are completely empty, but this is false economy. One of the most common flash exposure problems results from a lack of battery power during heavy use. If your flash does not recycle fast enough, for example, you will miss moments and have underexposed, motion-blurred images. Some photographers try to make a compromise by using rechargeable, high-capacity rechargeable AA NiMH batteries. There is something to this, as rechargeable batteries tend to keep full power for longer, especially the cutting edge 2700mAh MAHA batteries you can buy these days. A better solution than using individual AA batteries - especially if you're doing intensive photo shoots is to consider using external battery packs. Canon sells a Canon CP-E4 pack which goes with their flashes. They are quite bulky, but the amount of power you have available is much higher. The battery pack holds eight AA batteries, but because each individual battery is under less...

Neutralize nonactinic

A popular type of rechargeable battery for digital photography. A common problem with NiCad batteries is the memory effect,' which can occur if these batteries are recharged before they have been fully discharged. This causes the battery to prematurely experience a sudden drop in voltage, as if it has been discharged. nickel metal hydride (NiMH) battery. A type of rechargeable battery that can have two to three times the capacity of an equivalent size NiCad battery. NiMH batteries have an insignificant memory effect.

The Heroes The Lights

Gering device or directly synced to just about any professional camera. The SB-24 takes four standard AA batteries but also has a plug just under the red window on the front of the unit allowing a direct connection for highvoltage battery packs. The SB-24 is a bit bulkier than current models but is a great value if you can find one cheap. Nikon called this adaptation D-TTL flash. In all other measures, the SB-28DX is a great flash. It offers almost everything one would want in a portable unit it is smaller and lighter than the SB-24, 25, and 26 but offers the same power. Its power management (also known as the standby) mode was more advanced, and it was more frugal with its batteries. Of course, the SB-28DX can be dialed down to 16 power and has the front plug for direct connection with high-powered battery packs. In the last year or so, lightly used examples of this flash have come on to the used market in the 100.00 to 125.00 range. That's not a great bargain for someone determined...

Step 2 Selecting the Images

So, here are a few tips to help you quickly get to the earth-shattering moments of finally seeing your images. I have set up my laptop with the very same configuration as my desktop in my studio, which allows some luxury of familiarity between locations. I try to standardize as much of my processing protocol as possible so I can freely accomplish as much in the field as in the studio. Even so, I usually prefer to work on large files and projects at my desk with my larger screen and comfortable chair than on my laptop. On the other hand, good times can be had editing in the field. I do have very fond memories of editing on a porch with a view, a cool breeze on my face, a drink in hand and, of course, good tunes to set the tone. On cold nights, the warmth on my lap radiating from my laptop battery is always comforting.

How To Choose The Right System

The high-voltage cord for battery packs connects to the socket on the front of most Nikon professional flash units. Be sure to seat it all the way into the socket for the best connection. How do you know if your Nikon unit is professional If it has an HV socket on the front and a PC sync on the side, then you've got the real deal.

How do you know if your Nikon unit is professional If it has an HV socket on the front and a PC sync on the side, then you've got the real deal.

Useful specifications

Ideally the output of a professional unit will have a 'guide number' (an indication of the light output) of 25 or more. The amount of time the unit takes to recharge is also a consideration. Many flash outfits have the option of being linked to a separate power pack so that the drain on the unit's smaller power supply (usually AA batteries) does not become a problem. The flash head of a unit will ideally swivel and tilt, allowing the photographer to direct the flash at any white surface whilst still keeping the photocell pointed at the subject.

If you're lucky, you'll have a camera that can accept a rechargeable battery pack and use regular AA batteries as well. Some packs, like the one shown in Figure 6-6, are the same form factor as a pair of AA cells. (ftNG Of course rechargeable batteries need to sure that you have the proper adaptors for whichever country you're visiting. Don't automatically assume there will be plenty of outlets, either. I recently went on a Bahamas cruise and found that our stateroom had only one outlet. Because I'd come prepared with a power strip, we could still plug in my laptop, battery chargers, fan, and my wife's hair dryer and curling iron. Without such foresight . . . well, my wife and I would surely have ended up fighting over a single outlet. Another option, especially for those headed for a week or two in the back-country, is a solar-powered battery charger from ICP Global Technologies (www.icpglobal.com html pp.htm). This unit can charge four AA batteries in four hours or so, depending on...

Specialist SLR settings

Autofocus mode The default autofocus setting for digital SLRs is often continuous (or servo) mode.This continually tries to keep the subject of your shot in focus, reassessing and refocusing if it moves. There are two problems with this first of all, it doesn't do your camera's battery life any favours since autofocus requires a motor, and motors need large amounts of power. More significant is that it doesn't allow you to focus on a subject by pointing directly at it and then recomposing the shot - the servo focus will immediately refocus on what you're now pointing the camera at, which can be infuriating. Depending on how the focus area is set, it can also become confused by other objects moving in the frame and refocus on them apparently at random.

Prepare yourself This process requires great care and attention, so make sure you've found somewhere you won't be interrupted. You'll need to work on a stable desk, where there's no breeze, so close the windows and turn off any nearby fans or air-conditioning units. You also need plenty of indirect light - you should to be able to see exactly what you're doing, without exposing your sensor directly to bright light. Use the camera's menu system to enable the sensor-cleaning mode this flips up the mirror out of the way so you can reach the sensor. It doesn't hurt to make sure your camera has plenty of battery life left - if it runs out mid-clean, the mirror could unexpectedly flip down.

Having to give up halfway through a complex shoot due to dead batteries can be really frustrating. Try building foregrounds such as trees, cliffs, or old buildings into your image-these types of silhouettes form an interesting counterpoint to the circular motion of the stars.

Narrowband Imaging and Light Pollution Filters

In the few weeks since writing the above, I had a nasty incident that has caused me to think a little more carefully about the observatory electrical system. The supply from the house has an earth leakage circuit breaker for safety, and you really must fit one of these as the last thing we want is for you to be incapacitated in a remote observatory after receiving an electrical shock, and nobody knowing you are in trouble That wasn't the nasty incident by the way. The nasty incident was some power surges from a failing power supply spiking the mains supply. These spikes successfully took out the motor control board on the Celestron Nexstar 11 GPS telescope, and two complete sets of memory in two different computers This as you can gather was a very expensive glitch. In order to minimise this potential problem occurring again in the future I have fitted the Celestron Power Tank to the telescope this is basically a 12 volt rechargeable battery, so the scope is now completely isolated...

More power to your flash

You don't need me to say that, except for those of us fortunate to work in temperate or tropical climes, evening and night photography is synonymous with working in the cold And in cold weather, the battery power we rely on to power our kit tends to diminish almost in parallel with the encroaching cold. Additionally, lighting the darkness itself puts on onerous load on those batteries. It makes sense, then, to extend your power supply by using external, rechargeable battery packs. There are models to power most flash units and the batteries themselves are small enough to strap onto a belt. Better still, you can stick them in a pocket and keep them warm extending their life considerably. External battery packs also have the advantage that their inherently high power shortens recycle times and allows extended use even with highspeed digital cameras. With conventional in-board power, you always run the risk of a dark shot in a sequence, visible proof that the flash is...

Autopiloted Model Airplane

So far, the MAVinci team has developed two SFAP airplanes meeting different demands, a smaller one with a digital compact camera and a larger one with a calibrated DSLR camera, as prototypes for photogrammetric survey platforms (Fig. 8-42). For the smaller system, a Multiplex Twinstar II made from Elapor with a wing length of 1.4 m and a weight of 1.7 kg was adapted to accommodate the GPS INS control system and a Nikon Coolpix camera (ca. 200 g). The camera is completely concealed in the body of the plane and points vertically to the ground through an opening in the plane bottom. A single lithium-polymer (LiPo) rechargeable battery (11.1V, 5000-7000 mAh) provides power for the two propeller motors, the GPS INS, and camera, allowing a mission time of approximately 40 minutes or mission distance of 35 km. The battery as well as the camera memory card can be reached and removed when the cockpit cover is taken off.

Choosing the Best Camera for the

Ideally, you should choose a digital camera that runs on commercially available double AA or triple AAA batteries that you can find almost anywhere. Then, if you find yourself without power, you can just zip into the nearest convenience store and buy some more. If you already have a digital camera that uses proprietary batteries, try to make sure you have an extra battery or see if your camera comes with an external power supply. If it does, you can power it from your car's cigarette lighter in an emergency (either via an adapter or by using the power inverter described a little later in this chapter).

Using Multiple Light Sources

A more practical choice these days are monolights (see Figure 7.19), which are all-in-one studio lights that sell for about 200- 400. They have the flash tube, modeling light, and power supply built into a single unit that can be mounted on a light stand. Monolights are available in AC-only and battery-pack versions, although an external battery eliminates some of the advantages of having a flash with everything in one unit. They are very portable, because all you need is a case for the monolight itself, plus the stands and other accessories you want to carry along. Because these units are so popular with photographers who are not full-time professionals, the lower-cost monolights are often designed more for lighter duty than professional studio flash. That doesn't mean they aren't rugged you'll just need to handle them with a little more care, and, perhaps, not expect them to be used eight hours a day for weeks on end. In most other respects, however, monolights are the equal of...

Lesson 161Dealing with Toy Camera Characteristics

There are a number of issues to deal with when using toy digital cameras. The first issue is the lack of a true viewfinder. Most of the cameras do not have an LCD screen, and so you must contend with the optical viewfinder. In some cases, where you put your eye will change what you see through the viewfinder. Other cameras request that you hold the camera about 12 inches from your eye. It is sometimes difficult to get accurate composition. Figure 16.4 shows some of the resulting images from the problem viewfinders. Still, one of the endearing features of digital toy cameras is their unpredictability. Be sure to test your cameras carefully after you get them. The digital toy cameras have a tendency to go through batteries (typically AAA batteries) fairly quickly. Be sure to download your images right away as they are often only kept in memory. When the batteries die, the photographs may be lost. Remove the batteries after downloading the images if your camera uses them quickly. Some...

Supporting The Flash Units

Rechargeable batteries and AC power are the two most frequent ways to power electronic flashes. When there is no AC power anywhere close, using rechargeable batteries is an effective way to go. Of course, if you are using four flashes at one time and each takes four batteries, you need 16 batteries to power the setup, plus you need a second set of 16 batteries if you don't want to run out of power at an inconvenient time. Using batteries is a serious problem with multiple flash, but it does work if you have a second set of charged batteries and two or three battery chargers. It is preferable to use AC power, but many modern flashes are not designed to utilize this power so batteries may be your only choice.

The data, which was 3.73GB in total, transferred in a little over six minutes, meaning that as a rough guide the P-7000 takes around one and a half minutes to back up a gigabyte of image files. When we tested the previous-generation P-5000, we found that a 4GB San Disk Extreme III card copied in just under nine minutes. Annoyingly, though, the P-7000 cannot multitask while backing up. Once the process is underway, it is impossible to browse or edit files that have already been uploaded. This might not sound like a particularly serious criticism, but it may disappoint photographers who want to make the most of their 'down time' On the other hand, if you initiate a backup, then leave the viewer alone, it will shut down shortly after backup is complete, thus conserving energy.

The Macro Ring Lite is also equipped with twin focusing lamps and a set of 7 Custom Functions that allow you to modify flash operation for specific shooting conditions. The MR-14EX requires 4 AA-size batteries and is equipped with a socket for optional external power supplies such as the Canon Compact Battery Pack CP-E2 to reduce recycling time and increase the number of flashes per set of batteries.

Charge Your Battery

When you first open your camera and slide the battery into the battery slot, you will be pleased to find that there is probably juice in the battery and you can start shooting right away. What you should really be doing is getting out the battery charger and giving that power-cell a full charge. Not only will this give you more time to shoot, it will start the battery off on the right foot. No matter what claims the manufacturers make about battery life and charging memory, I always find I get better life and performance when I charge my batteries fully and then use them right down to the point where they have nothing left to give. To check your battery level, insert it into the camera, turn on the camera, and look for the battery indicator in the top-right section of the information screen (Figure 1.1).


Proprietary, built-in rechargeable. Many smaller cameras come with a brick battery a dark gray, lithium-ion rechargeable battery, as shown at top in Figure 1-2.

When the main battery gives up the ghost, swap it with the one in the charger, and go about your business. For a full day at the theme park, fully charge both batteries and take them with you. All this recharging roulette is a pain, but it beats any system in which the camera is the battery charger, which is the case with some cameras. When the battery dies, so does your creative muse.

Basics of Cameras

The last part of the camera is the power supply. There are several types of battery systems, including standard batteries (such as AAA) and rechargeable battery units. The power supply is often overlooked, but it is important because all of the integrated systems within the camera use the electrical energy provided by the power supply. Although cameras and batteries are becoming more efficient, many aspects of taking digital images drain the batteries. The use of an LCD viewing system is one of the most taxing demands on the batteries.

Battery Included

Your Sony Alpha dSLR is a sophisticated hunk of machinery and electronics, but it needs a charged battery to function, so rejuvenating the NP-FH50 lithium-ion battery pack furnished with the camera should be your first step. A fully charged power source should be good for approximately 500 shots under normal temperature conditions, based on standard tests defined by the Camera & Imaging Products Association (CIPA) document DC-002. If most of your pictures use the built-in flash or you are using Live View mode with the A390, you can expect about half as many shots before it's time for a recharge. While those figures sound like a lot of shooting, things like picture review can use up more power than you might expect. If your pictures are important to you, always take along one spare, fully charged battery. And remember that all rechargeable batteries undergo some degree of self-discharge just sitting idle in the camera or in the original packaging. Lithium-ion power packs of this...

Little History

No, the real first digital camera was created by a guy named Steve J. Sasson, who slaved away in Kodak's Research Labs in the mid-1970s (and is still there by last report). Sasson built the first known digital camera, roughly the size of two shoeboxes and weighing 8.5 pounds. It contained 16 AA batteries, a bunch of circuit boards, a new Fairchild black-and-white 10 kilopixel sensor (a 100 X 100-pixel array), and had a lens sticking out the front. It took 23 seconds to record a single image onto a cassette tape. I checked out the patent application for this remarkable device. You can too, at http www.uspto.gov . Search for Patent 4,131,919.

Prepping Your Camera

All digital cameras require a battery or batteries to operate. If your camera doesn't have rechargeable batteries, simply insert the set that came in the box. If your camera doesn't turn on once you have inserted fresh batteries, check the polarity of the batteries (the + - top or bottom) to make certain that they're installed properly. Many models come with rechargeable batteries that must be fully charged before you use your camera for the first time. Depending upon your make and model, you may simply plug the camera into a wall outlet, drop it into a camera dock or cradle, or place the batteries in some sort of external charger. By the way, most rechargeable batteries come partially charged, so you can turn the camera on for a brief period. But to operate the camera properly, it will need a full charge, which can take anywhere from an hour to 8 hours, depending upon the type charger that came with your camera.


The lighting you need depends on where you will be photographing. If you have a digital SLR camera, an adjustable, automatic electronic flash is something you will use nearly all of the time, both indoors and out. A really good quality unit will cost about 300 and will handle most of your needs. A top-of-the line professional unit with separate battery pack is about 1,000 and is probably more than you need for boudoir portraits. If you will be doing studio work, then either hot lights or studio flash equipment with softboxes and umbrellas will be something that you'll want eventually. If you are just starting out, keep it simple and inexpensive and learn as you go along.

Carrying that weight

With the exception of some tiny models from Pentax and a few other vendors, digital SLRs are bigger, heavier, and clunkier than pocket-sized point-and-shoot digital cameras. The more you spend on a dSLR, the bigger it's likely to be, too, because vendors offer magnesium alloy bodies instead of the composite plastic used for entry-level digital SLRs. Tack on extra battery packs and special grips that let you shoot more comfortably in a vertical position, and the camera becomes even larger.


This is where your notebook comes into play and helps to eliminate the limitations of a conventional studio setup. An LCD monitor can immediately provide you with any background image you like and, if your computer batteries have enough juice, with additional lighting too, making you independent of fixed power supplies or wall outlets.

Power Sources

Digital cameras devour batteries, especially when the LCD monitor is used often, making the familiar alkalines virtually useless because of their low power output. You'll want a camera that accepts high-capacity batteries either in the AA size or some unusual size shape in a proprietary battery pack. Rechargeable Lithium Ion or Ni-MH (Nickel Metal Hydride, see

Control Panel

Usually found only on higher-end cameras or, conversely, very inexpensive models that don't have an LCD viewfinder, the control panel (see Figure 3-6) is a small grey screen on the top of your camera (or sometimes on the back above the LCD), which continuously displays lots of information, such as exposure settings, the battery status, the flash mode, the number of frames left, and so on. Most of the same info is also displayed on the LCD (when it's turned on and in the proper mode), but it's always visible on the control panel. Sometimes, there's a nearby button, for briefly illuminating the control panel.

LCD viewfinders

In a non-SLR, the liquid crystal display, usually measuring 1.5-2.5 inches diagonally, shows an electronic image of the scene as viewed by the sensor. (Digital SLRs can't preview images on their LCD because the mirror, shutter, and other components get in the way of the sensor until the moment of exposure.) On the one hand, that's good because you can view more or less the exact image that will be captured. It's also not so good because the LCD screen is likely to be difficult to view, washed out by surrounding light, and so small that it doesn't really show what you need to see. Moreover, the backlit LCD eats up battery power. I've used digital cameras that died after 20 minutes when the LCD had depleted their rechargeable batteries. Luckily, some digital cameras let you specify that the LCD is turned on only when composing a picture or only for a few seconds after a picture is taken (so that you can quickly review the shot).

Camera Batteries

Most digital cameras come with a rechargeable battery and charger. Always order at least one extra battery. You need a spare since rechargeable batteries tend to work fine for quite awhile and then suddenly fail with little warning. If you go on any expensive or time-consuming photo trips, take three or four spare batteries with you. How many shots can be taken with a single battery depends on many variables. Using autofocus, image stabilization, and viewing the LCD monitor all consume battery power. If you are getting short on battery power, turning off some of these will make the battery last longer. Cold temperatures lower the ability of a battery to run the camera. In cold weather, if your battery fails and you don't have a spare, try putting the battery inside your coat to warm it up. Once the battery is warm, it should continue to operate the camera, until of course, it gets too cold again. Temperatures below zero are common in Yellowstone National Park during late January and...

Compact Cameras

Some of their disadvantages include heavy noise (even at moderate ISO speeds), low battery life, slow autofocus, shutter lag, and non-interchangeable lenses of often disappointing quality. Many of these cameras do not offer a viewfinder, using the LCD screen instead for composition, which leads both to great framing difficulties in direct sunlight (especially when snow and sunglasses are involved) and to increased power consumption. Finally, all but the most expensive models offer little manual control and no possibility of shooting in RAW format, relying instead on JPEG and dumbed-down program modes, forcing photographers to spend as much effort working around the quirks of the camera as they do on composing the images.

Lite Bright

( 260 street) replaces the comparatively limited 420EX flash, and dramatically raises the bar for amateur flash units. Distinguished as Canon's first nonpro accessory flash dedicated to digital, the 430EX sends white-balance information to compatible digital SLRs and adjusts its autozoom settings to maximize efficiency with sub-35mm sensors. For example, when used on the Digital Rebel, it knows to emit a narrower beam at a given focal length than when it's used on the Elan 7n. The benefits somewhat longer throw and battery life.

Choice of flash

Perhaps the most important consideration when selecting an automatic flash unit is its ability to make use of a range of f-stops on the camera lens. Cheaper units may only have a choice of two f-stops whereas more sophisticated units will make use of at least four. Ideally the output of a professional unit will have a high 'guide number' (an indication of the light output). The amount of time the unit takes to recharge is also a consideration. Many flash outfits have the option of being linked to a separate power pack so that the drain on the unit's smaller power supply (usually AA batteries) does not become a problem.

Power supply

Digital cameras can be remarkably compact, especially scientific grade types that can be of 'lipstick' size, where only the lens and sensor array are encapsulated together, then the control signals, power supply and data output are transmitted by a tethering cable to a camera control unit (CCU) or a PC. The sensor head can be on a long cable connecting it to the body with its LCD viewfinder. Power is needed for all camera functions, including the CCD array, shutter, circuitry, displays and storage. An adequate power supply may be bulky and a battery pack take up much volume in the camera. A rechargeable battery may be recharged in the camera, and is preferably a lithium ion type with no charge memory problems. Nickel metal hydride types are an alternative. A separate battery pack may be useful and used attached to a belt. Separate digital backs for cameras are powered via a tethered connection to a PC.

Samsung Ncio

As Netbooks go, the Samsung NC10 is on the larger size, but that does mean the keyboard is less cramped and you get a larger screen, if not a higher resolution than average. Performance is good and battery life excellent, offering over seven hours of continuous use, though the extra large battery does push the weight up to over 1,3kg. With an attractive price, great performance and battery life, plus a generous 160GB hard drive, the NC10 is the pick of this Netbook bunch.

Other Accessories

It is often difficult to judge in advance how long a shoot will take, and dead batteries in the middle of a complex sequence can be really frustrating. If you know a little about hobby electronics, you can also build more complex lighting rigs with, for example, with blinking lights. Once again, the Internet is a great source of ideas and resources for circuit diagrams as well as for purchasing components.

Good Things to Know

The battery compartment cover is on the bottom of the camera. One rechargeable lithium BP-511 (or 512) battery pack will capture over 600 images in warm weather when not using flash. The battery compartment cover is on the bottom of the camera. One rechargeable lithium BP-511 (or 512) battery pack will capture over 600 images in warm weather when not using flash.

Spare Batteries

One of the drastic improvements in DSLR design, is the improved life of batteries. Camera batteries should now last all day without replacement. However, it's always a good idea to bring extra batteries and a charger or two. Spare packs should be fully charged and ready to go and you should have enough to handle your cameras as well as your assistant's cameras and the backup gear. If downloading images to a laptop, do not forget spare laptop batteries or the computer's AC adapter.


These are the newest player on the battery scene.There are two varieties of lithium batteries, so be careful not to confuse the two when battery shopping. Both of them have a high capacity, a long shelf life and are designed for highdrain devices such as digital cameras. However, Lithium batteries are not rechargeable, while Lithium Ion batteries are. Lithium Ion batteries are certainly a better investment, but they aren't yet available in all of the common battery sizes such as AA or AAA.They are typically only available as specially made battery packs that only fit one particular camera. Plus, they are only thought to last for two to three years. Non-rechargeable Lithium batteries are available in more popular sizes, but they will end up being an expensive and wasteful option.

Pentax K100d

Pentax doesn't claim any improvements in battery life for the K100D, despite the newer processing engine. That leaves this camera in the same unfortunate battery condition as the *ist DS2, which has a CI PA rating of only 70 shots when loaded with four AA alkaline cells. We highly recommend buying a set of 2000 mAh (or higher capacity) NiMh AA rechargeables to boost the shot capacity-especially since the KIOOD's shake reduction (SR) system will drain the batteries even faster.

The Rechargeables

RECHARGEABLE BATTERIES used in cameras and flashes today come in various shapes and sizes, and all are generically identified by their chemistry. The three major types lithium ion, nickel-metal hydride, and nickel cadmium are described in the table below. And while each has its faults, any rechargeable is probably better than nonrechargeable alkaline cells, which, especially with power-draining digital cameras, can become expensive over the long haul.


According to the EPA, each year over 2 billion used batteries are disposed into solid waste facilities in the United States. This constitutes 88 of the mercury and 54 of the cadmium deposited into our landfills. Many kinds of batteries, like those used in digital cameras, can be recycled instead of thrown away. When they wear out, try to take them back to the store where you bought them. Many stores collect the used batteries and then send them to a factory to be recycled. If not, contact local health officials to see if any provisions have been made for battery disposal.

Battery Choices

Battery life depends extensively on age, usage conditions, type, brand, and camera. Digital cameras are dependent on battery power, but not all batteries perform well in digital cameras. Nickel-metal hydride (Ni-MH) and lithium ion (Li-ion) rechargeable batteries deliver the best results in a variety of conditions. Ni-MH and Li-ion batteries are designed for high-demand devices, like digital cameras, and do not exhibit the memory effects seen with other recharge able technologies. Memory effect is when a battery remembers how full it was when it was last recharged and does not go past that point the next time it is charged. This problem can be reduced by completely draining the battery before recharging to insure the longest charge. Regardless of type, one of the best strategies to prolong battery life is to use them. Otherwise, they will lose their capacity to hold a charge.


The only things you need to check in selecting a camera are to see how visible your camera's LCD display is in bright daylight, whether it is large enough to view easily (most digital cameras use a standardized 1.8-inch LCD component), and the amount of power it consumes. The LCDs on some cameras consume so much power that, if the camera is left on all the time, you may find yourself with dead batteries after only a dozen or so shots. Active matrix displays are among the brightest and most power-efficient. Some cameras let you turn on the LCD display only when it is required to compose a picture.

Other Features

Once you've chosen your must have features for your digital camera, you also can work on those bonus features that are nice to have, but not essential. For example, some digital cameras let you add a voice message to annotate your images with a few seconds of sound. Others may let you record short video clips at low resolution (say, 320x200 pixels). Many have video outputs so you can view your pictures on a TV screen without transferring them to a computer. This is great for previews, and can turn your camera into a portable slide projector If you shoot many pictures, the ability to choose from cheap alkaline batteries, which you can pick up anywhere in a pinch, to more economical high-capacity rechargeable batteries will be important. Bonus features like these are seldom factors in choosing a camera, but all other things being equal, they are frosting on the cake.

Would you like to get really creative with your underwater photography and have full manual control over your settings to change both the aperture and shutter speed of your camera to achieve darker backgrounds with your photographs Or if you are shooting with a strobe, being able to adjust the aperture settings on a compact is absolutely essential to control the lighting of your...
