I guess my question is..if one did find that the histogram was clipped in 
Photoshop what is it that one would do in the Insight scanning software in 
order to go back and rescan the image so that the histogram was no longer 
clipped.  What adjustment would be made in the scanner software prior to 
rescanning in order to get it right?
