Histogram Sheet
When the Histogram button is clicked, the Histogram sheet is
displayed.
Use the histogram to enhance an image when the image is either too
light or too dark, like an overexposed or underexposed photograph.
Increasing the darker tones with the histogram improves the contrast of
the image.
Channel
If you want to select one of the primary colors (RGB) for adjusting the
histogram, click the Channel down-arrow and select the color, or leave
the setting at Master to adjust all colors.
