The Dynamic Range dialog box
By default, this tool automatically determines the lightest density or tone (Dmin)
and darkest tone (Dmax) of the original; then it captures the image color data
(histogram area) with the full input tonal range of the scanner. This setting
optimizes color balance and the contrast of the output image, and is most useful
for scanning negative films. You can override the auto-settings by defining your
own custom dynamic range (Dmin/Dmax) values to all or each individual RGB
channels. Manual setting tools are provided in the AIC Dynamic Range
