Shutter Speed And Motion

To make a sharp picture of a subject in motion, you need a fast enough shutter speed to freeze the motion. How fast is fast enough This depends on several things. Look at this sequence of photos of a motorcycle going about 30 mph taken at 1 15, 1730, 1 60, 1 125, 1 250, 1 500, and 1 1000 of a second. The shorter the exposure, the sharper the image. At 1 1000 we have certainly frozen the image. But is that the effect we w ant Maybe, and maybe not. Let's say that our desire is to express the...

Selecting Your Shutter Speed

Your choice of shutter speed to photograph motion depends on four factors 1. The speed of the moving object. 2. The direction of the moving object. 3. The distance of the moving object. 4. The focal length of your lens. 1. Speed of moving object. Obviously, the shutter speed required to stop the movement of a marathon runner is a lot less than the shutter speed required to stop the movement of a speeding bullet. You need to use a shutter speed that's appropriate to the movement of the object....

Shutter Speed

You know that the twin poles of setting exposure are aperture and shutter speed. In your next Unit we'll show you how to achieve absolutely perfect exposure in every picture you shoot. In this lesson, however, we want to introduce you to aperture and shutter speed individually, and examine how you can use them to achieve very specific creative goals. To this point, we've discussed aperture and how you can use it to control depth of field. Now let's turn our attention to shutter speed. The...

Portfolio

How The Pros Use Depth Of Field Creatively. Depth of field can be very deep or very shallow or anywhere in between. In this portfolio we explore how different photographers vary depth of field to produce different effects. Above. A limited depth of field has emphasized the visual weight of the woman in this photograph by Charles Moore. By focusing sharply at a wide aperture, the photographer has pulled the woman forward out of a busy scene and riveted our attention on her. The man to the left,...

Self Check Quiz

This brief Quiz is designed to enable you to check your understanding of the information in this lesson. Answer all the questions in this True-or-False Quiz. Then check your answers on the back of this page. Next to each answer, you will find the page reference on which the relevant material is discussed in this lesson. If you get one item wrong, read the page relating to your wrong answer. If you get two or more wrong, read the appropriate pages, then reread the en tire lesson. Then take this...

Vision problems

If you still have difficulty achieving pictures in sharp focus, don't rule out the possibility of a vision problem. Even without vision problems, some photographers actually prefer autofocus cameras because they find them more accurate. If you have vision problems, consider diopters, which are magnifiers that screw into the camera's viewfinder. These diopters magnify the image and may be helpful. If you wear bifocal eyeglasses when you photograph, always focus through the distance part of the...

Rangefinder Focusing

Rangefinder cameras have been around for more than half a century. They were the basic focusing device used by most early 35mm cameras and they are still used on today's popular Leica M series of cameras. Rangefinder cameras use a combination of mirrors and levers that link the image reaching the film to the image you see in the viewfinder. If the film-image is out of focus, you see an imperfect image in your viewing window. Either it's a double image, similar to the ghost on a TV screen, or...

Types Of Shutters

Types Shutters Camera

There are two principal types of shutters The between-the-lens shutter consists of a series of thin steel blades set between the elements of a lens. The shutter release button activates a spring that snaps the blades open for the duration of the exposure, then shut. This type of shutter is also called a leaf type shutter. Between-The-Lens or Leaf Type Shutter Between-The-Lens or Leaf Type Shutter The focal-plane shutter is located in the camera, directly in front of the film. It is directly in...

Optical Viewfinder And Rangefinder

Viewfinder Rangefinder Camera Diagram

In your last lesson you were introduced to a powerful technique you can use to gain enormous creative control over your images -namely, the focal length of the lens you use. We showed how you can use a wide-angle lens to produce a heightened sense of distance and you can use a telephoto lens to produce a flattening effect. In this lesson, you're going to add two more techniques to your arsenal of creative controls 1. Creative use of depth of field. 2. Creative use of shutter speed. You probably...

Twin Lens Reflex TLR

When you peer into an optical viewfinder or rangefinder v camera, you see a reasonably clear image of the intended subject. But the size of that image is limited by the generally small dimensions of the viewfinder window. The image you see is unrelated to the actual size of the image that will strike the film to produce the negative. The twin-lens reflex TLR produces an image that is virtually identical to the film-image size, and operates as follows As the name implies, the TLR has two lenses,...
