Determining filter adjustment
(3) The effect of filter changes on exposure must be kept in mind.
For example, if diffused whites in a test print are reddish, it may work
well to add 10M + 10Y to the pack and to use the same exposure.
other hand, correcting the color balance by removing 10C will definitely
call for a decrease in exposure.
(4) With experience, exposure adjustments can be estimated fairly
accurately when the test print is close to the desired density and color

filter changes is given in figure 3-2.
e. Electronic Evaluation of Print Color. While color correcting by the
use of viewing filters is suitable for print evaluation in a small
production facility, electronic techniques may be more practical for labs
with a higher volume of work. Electronic methods include on-easel and off-
