Hmmm -- that is not what I thought. When I do print, I have been resizing and resampling, then sharpening at the resampled resolution, viewing the image on the screen at 1-1 pixel resolution. What should one do about sharpening if one does not resample? - -- Clive http://clive.moss.net - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
