Brightness & contrast variation
Eight images with a slight correction to brightness and contrast are displayed around a thumbnail of
the original image. Brightness controls how light or dark the image is. Contrast controls the difference
between the tones of the image; as the contrast is increased the dark tones will become darker and
the light tones will become brighter. Contrast also affects the apparent sharpness of the image.
Drag the variation-step slide bar, or enter the correc-
tion level into the text box to set the degree of correc-
tion.
• The initial setting is 10. The correction step can be
set between 1 and 20.
• Checking the display-limit check box will indicate
when any of the image values exceed 0 (black limit)
or 255 (white limit) with the complementary color.
For example, if the white area of the image exceeds
those values, the limit is displayed with the
complementary color, black.
Click the best image among the eight frames.
• The selected image becomes the new center
showing eight new images corrected by the
designated step. This procedure can be repeated
until the desired correction is obtained.
• Click the reset button to cancel any changes.
Click the close button to close the palette and apply
any image corrections.
