Adjusting a Histogram
The histogram adjustment mode is available when the color mode is set to
[42-Bit Color]
,
[24-Bit
Color]
,
[14-Bit Grayscale]
or
[8-Bit Grayscale]
. The histogram shows just how much data falls into
each brightness level. Use this mode when you wish to specify the appropriate allocation of data
between the brightest values (highlights) and the darkest values (shadows). You can specify cutoff
values for highlights or shadows to create a better distribution of the halftones.
