HIGHLIGHT/SHADOW LEVELS

Images have light and dark areas. The highlight is the lightest spot on an image; shadow is the darkest spot. The range of colors between the highlight and shadow determines the range of colors of the image. Using the Highlight/Shadow Levels features, however, you can extend the original range of colors between the highlight and shadow to reveal more details in the midrange colors.

To adjust the highlight and shadow levels:

1.Click the Highlight/Shadow button.

The dialog box that appears shows a histogram of the saturation, gamma, and hue (S, G, H) of the range of colors for the highlight and shadow.

Saturation is the strength or purity of a color, gamma controls the brightness of the midtones of the color, and hue is the color your eyes see as reﬂected from the image. The gamma setting in this dialog box is in conjunction with the hue and saturation but you can also set gamma by itself for an image. See the section “Curves,” below for more information

2.From the Channel drop-down menu, choose RGB to adjust all the channels together, or choose a single channel if available.
