Konica Minolta IV instruction manual

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.
