This image is flat. The pixel distribution in the his-
togram 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 his-
togram. 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.
