NOTE:  Choosing the True Color RGB 36-bit setting captures more data than the 24-bit setting.  This 
means that the file sizes listed above will be larger if you scanned images using the True Color 36-bit RGB 
setting. 
Choosing the Best Resolution for Your Scanning Project
 
 
To choose the best resolution for scanning, determine what you are gong to do with the image once it is 
scanned.  Matching your scanning resolution to the image use will give you the best image for that purpose 
and will keep the file sizes to the minimum needed.
