Exposure:
The Exposure setting lightens or darkens an image. You can
select from -10 (darkest) to 20 (brightest) by moving (clicking
and dragging) the slider.
The Exposure and Highlight controls are related. When the
Exposure setting is changed, the Highlight value is
automatically set.
Gamma:
The Gamma contrast allows you to adjust the mid-tones in an
image. You can select from 50 (lowest) to 500 (highest) by
moving the slider.
Highlight:
The Highlight control allows you to adjust the brightness
level of the brightest parts of an image. You can select from
61 to 490 by moving the slider.
Click the eyedropper button beneath the slider, and the
mouse pointer changes to an eyedropper. Move the
eyedropper over the preview image, and click a bright area.
The eyedropper “picks up” the color from that area, and uses
it as the highlight for the entire image. This effect shows up
immediately in the preview image. Click Cancel to restore
the original image.
Shadow:
The Shadow control allows you to adjust the darkness level
of the darkest parts of an image. You can select from 0 to 60
by moving the slider.
