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.
