Changing highlights
The highlight is the value in the image that is represented on the
screen as white. All values lighter than the highlight also appear as
white.
The image has a default highlight setting. Selecting a higher number
makes more of the lighter values distinct, which increases detail in light
areas. Selecting a lower number makes fewer of the lighter values
distinct, which reduces detail in the light areas.
To adjust highlights for slides, negatives, or other transparent items,
use
