This image is flat. The pixel distribution in

the histogram reflects the low-contrast

scene. The lack of any strong shadows or

dark tones is indicated by the absence of

pixels on the left of the histogram. Most of

the detail is concentrated in a narrow range

in the mid-tones.

By moving the shadow slider to

the right to set the black level to

where the pixel distribution

begins, image contrast is

improved.

The gamma slider can be used to change the relative distribution of the tones in the

image. By moving the gamma slider to the left toward the shadows, the image

becomes lighter. By moving the gamma slider in the opposite direction, the image

becomes darker. However, unlike the brightness control in the brightness, contrast,

and color-balance palette (p. 40), details are not lost in the shadows or highlights.
