Editing and Retouching
The toning tools consist of the dodge tool and
•
the burn tool. Used to lighten or darken areas of
the image, the dodge and burn tools are based on
a traditional photographer's technique for
regulating exposure on specific areas of a print.
Photographers hold back light to lighten an area
on the print (dodging) or increase the exposure to
darken areas on a print (burning).
Burning an image, and dodging an image
The sponge tool subtly changes the color
•
saturation of an area. In Grayscale mode, the
sponge tool increases or decreases contrast by
moving gray levels away from or toward the
middle gray.

saturation, see figure 8-1 on page 227.
