The advantages of going to 10 or 12 bit images is the additional processing [ie. edge enhancement, etc] that can be done w/o loss of information. There is no reason to spend the money on 10 bit DACs to your monitor, but there is often justification to use 10 or 12 bit ADCs on input. rich ======================================================================== Richard Fozzard "Serendipity empowers" Univ of Colorado/CIRES/NOAA R/E/FS 325 Broadway, Boulder, CO 80303 fozzard@boulder.colorado.edu (303)497-6011 or 444-3168
