Without color information it would be difficult to process after the fact. I'd imagine that the gain over a color CCD would be a somewhat greater pixel density and/or better signal/noise ratio if the individual cells are a bit larger than those in the color CCD's cells. I think I'd go for larger cells to catch more light - better sensitivity. Adam - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
