The Histogram Color Pickers
e histogram color pickers enable you to point at any pixel in your
preview image and assign the highlight, neutralize, or shadow point
based on the value of that pixel. Both the highlight and shadow color
pickers will affect the brightness and contrast in your image by choosing
the tonal range.
To use the color pickers:
1. Click on the appropriate eyedropper button for the type of tonal
range setting you would like to make. Your mouse pointer turns into
the selected eyedropper.
