Shadows and Highlights
This tool lets you adjust the shadow and highlight areas of an
image, allowing you to select a new shadow point to become
the darkest value, or a new highlight point to become the
lightest value. The effect of this is to bring out more visible
detail in an image, especially if it has only a limited range of
grays or colors.

Curve
This tool lets you modify the gamma, which is the contrast
affecting the middle range of grays in an image. The Curve
tool lets you modify the midrange of grays without dramati-
cally altering the shadows and highlights. Using a combina-
tion of the Shadows and Highlights tool together with the
Curve tool gives you the most precise control for adjusting
the tonal values of your image.
