(1) On-easel.
This technique is done by reading densities of the
negative in either a small spot or a large area of the negative. This is
done by placing a probe on the enlarging easel while the negative is being
projected over it.
Correct settings for density and filtration can be
obtained by this method.
(2) Off-easel.
Use a densitometer to determine color from a
negative; by this method, an operator can supply printing data to the
darkroom workers thus freeing him up to print rather than tie up the
enlarger doing color analysis. This method is useful when there is a high
volume of production.
f. Using a video Negative Analyzer. Another method of off-easel color
evaluation is a video negative analyzer which translates the negative into a
high quality positive color television image.
This television image
presents the color balance and density of the print that would be made from
the negative being evaluated, so that the print requirements may be
determined.

Dodging/Burning-in.
You know that filtration influences the overall color balance of the print.
Local density can also be altered by using filters.
You can change the
color of a small area by dodging with a filter in the path of the light
source.
a. Choosing Filters. You can lighten a color in the print by dodging
it with a filter of the same color. For instance, you can lighten the green
grass in a scene by dodging with a green filter. Likewise, you can darken a
specific color by dodging with a complementary colored filter. You may wish
to darken the sky.
You can do this by dodging the area with a yellow
filter.
b. Using Normal Dodging and Burning-in Techniques.
You can also use
normal dodging and burning-in techniques.
However, burning-in and dodging
may alter the color balance in addition to making it darker or lighter.
Here again, experience is the best teacher.
