The Auto Contrast Selection
The Auto Contrast feature will automatically scale the black and white values of an
image to more tightly fit the gray scale intensity profiles (histogram). This selection will
use different black and white values for different images depending upon their unique
histograms. A more dramatic visual change will take place for low light level images
(such as chemiluminescence) where smaller portions of the histogram are used. This
selection can be turned on or off and will adjust differently for each image.
