e. After you select the filter adjustment, you must decide how much of a change is required.
Refer to Table 3-4 as a guide to the degree of adjustment.

Learning Event 3:
DETERMINE THE TYPE OF EVALUATION METHOD
1.
There are various methods utilized in making color prints; all producing satisfactory results. The
printing steps for color are essentially the same as in black and white printing. The main additional
factor that must be considered in color negative printing is the required use of filters. Once the use of
filters is understood, color printing can be relatively simple. Once the use of filters is understood, color
printing can be relatively simple. There are two evaluation methods, visual and densitometric.
2.
The different evaluation techniques provide a method of reading the blue, green, and red
densities of the negative and print. These values provide the data you need to adjust the densities of the
CP, CC, or dichroic filters. When the print material is exposed, the blue-, green-, and red-sensitive
layers of printing material receive the proper exposure.
a. The visual method of evaluation is also called the trial and error method and uses various
filters. This method of evaluation is not the most accurate and requires guesswork in determining print
filter packs and exposure. However, to understand the theory in making color prints, the visual (trial and
error) method will help you to understand what is taking place when color densitometers, color
analyzers, and color video analyzers are used for mass production. This is the method usually used in a
small lab.
(1) After print is made, you view the print through a series of filters (fig 3-1). These filters
alter the color of the print. The print should be viewed under daylight fluorescent lighting. Warm, soft,
fluorescents or regular tungsten household lamps will give a wrong color balance.
