Adjusting For Filter Factors

This relates to using acetate filters, not to a dichroic color head. Let's say you want to produce 60Y. If you have a single filter marked 60Y, use it. But, more likely, the strongest filter in your kit is 50Y. To produce 60Y, combine two filters for example, 50Y and 10Y or 40Y and 20Y. While you could produce the same 60Y by combining three or more filters for example 30Y and 20Y and 10Y this is not so good because the reflective surfaces of each additional...

Color Lab Services

All photographers, whether amateur or pro, will occasionally have film processed or prints made by a commercial lab. And some photographers including many pros will use commercial lab services for all their pictures. So let's discuss what these labs can do for you, and how to choose the right type of lab to meet your needs. We suggest you also review the lesson on The Perfect Print. Basically, there are two types of labs Commercial photofinishers are generally large labs that are geared to...

Printing Step by Step

For your first print you'd probably like to use your all-time favorite color-image that glorious sunset, your dog's crossed eyes, the macro shot of a bee on a rose. But hold on a second. You'll get to print that favorite shot later. Your first image may have to be something more prosaic because you should be able to use your experience from printing this first image to help you print subsequent images. So we want you-to choose an image that can become your...

Processing Drum

For the small darkroom, there has been one simple innovation in recent years that has made color printing much easier, safer, and more economical. The way you will approach color printing stems from the introduction of the plastic processing drum, which is simply a sealed plastic cylinder that can process one or more prints at a time with a tiny amount of fresh chemical usually just IV2 to 3 ounces. In addition, since the drum is light-tight, once the exposed paper is put into the drum and the...

How To Use The NYI Ringaround

On the NYI Color Printing Guide you will find the Filtration Ring-around. This series of 13 pictures can be extremely helpful when you are trying to decide how to adjust your filtration. Very often, when you look at a print, you can't quite tell its exact color cast. For example, it may appear sort of greenish. But is it greenish or bluish or cyan-ish The choice can be difficult, and that's where the Ring-around can help. , Hold your test print up next to the pictures in the Ring-I around....

Processing With Cibachrome

For the Cibachrome-A II process, use only Cibachrome Process P-30 chemicals. The earlier Cibachrome materials used Process P-12 chemicals. While you might still see those chemicals in a store, they cannot be used with the new paper. Process P-30 consists of three chemicals developer, bleach, and fixer. These are mixed from six components, five of them liquid. All the chemicals can be mixed using tap water from 68 to 84 but for dissolving the powdered bleach chemical, use warm water from 75 to...

Stability Of Color Films And Prints

Once you have made a color print or transparency, you should feel that it will last forever, an eternal memorial to your talent. Nothing could be farther from the truth. Color negatives, color transparencies, and color prints are all subject to fading. This is because the dyes in all of them are composed of large complex molecules that are inherently unstable. This instability, and the color-fading it produces, are classified into two separate categories 1. Dark-fading. This type of...

Kodak Color Print Viewing Filters

In addition to the Beseler Universal Color Calculator there are two other matrix-type calculators currently on the market Kodak's Filter Finder and Unicolor's Duocube. The Kodak Finder is somewhat impractical for the following reason. Instead of averaging out the color-mix of the image by using a white diffuser during printing, it requires that you, in effect, average out the color-mix when you shoot the image by including a gray-card in the scene. Then, to use the Finder, you project onto it...

Shooting Your Own Standard Negative

As mentioned earlier, you will probably get better results if you shoot your own standard negative. In the old days Kodak supplied a perfectly exposed, perfectly printed Vericolor II reference negative with their publication, The Color Darkroom Dataguide. Known to generations of photographers as a Shirley not related to your beloved mannequin, Shirley this reference negative is no longer supplied with the Dataguide, but is available for purchase separately. Today, with the many different film...

Using A MatrixTVpe Calculator

If you don't understand it, don't worry. You can still use a calculator effectively if you just follow the step-by-step procedures outlined in the instructions that come with your calculator and look for the gray square in your test print. Here are the basic procedures for the Beseler Universal Color Calculator, which is fairly typical The Beseler Calculator is a flat piece of plastic 4x5 containing 127 transparent acetate squares. As you can see in the picture, each square...

Darkroom Timer

The real question is not whether to buy a processing drum, but which brand to buy Although most drums are similar, there are some factors to consider. Drums are available in different sizes designed for different-size prints. Usually, the larger-size drum can also accommodate smaller-size prints, too. For example, a tank designed for 11x14 can usually also handle up to two 8x10's or four 5x7's. But realize, you may want to process your 8xl0's or 5x7's one at a time. While you may do so in an...

Kodak Projection Print Scale

Projection Print Scale

One way to run a quick test print to determine correct exposure is to make your first print using a simple acetate screen called a Kodak Projection Print Scale. Here's how it works The scale itself is a piece of transparent acetate on which is printed a circle measuring 4 inches in diameter. This circle consists of black dots of varying density that form a pattern similar to wedges in a round pie. To use the scale, you set up your enlarger to make a print in the normal manner. Set your...

Enlargers And Color Filters

The colors you produce in your print are determined for the most part by the color-mix of the light striking the paper. You must control, and may need to vary, this color-mix for each and every print. In fact, this is really the only challenging part of color printing since all the other steps are more-or-less routine. How do you change the color mix of the enlarger light The least expensive method is by placing a colored sheet of transparent material in the light path. To facilitate this, most...
