Dynamic Range tool (LCH & Native color mode)
The Dynamic Range tool is used to set the density capture range of the scanner
and displays the density distribution (histogram) of the image to be scanned.
The Auto range (default) feature automatically determines the Dmin (minimum
density, lighest tone) and Dmax (maximum density, darkest tone) of the image,
and sets the scanner capture range.
