The Leaf Lumina - it took only the info from the green filtered section of the trilinear CCD to the AD converter. Anyway, Austin, I further stated that it was faster also because there was less data to move around. And then when I stated: > But with some lame scanners scanning RGB then converting back to > grayscale can help with stubborn negs.

Are you suggesting that because you can do the >>conversion better in PS that what is done in the scanner? What would be >>"stubborn" in a negative that would "necessitate" that? Austin, this is from my experience using lots of different scanners over lots of years. I suggest you try it yourself before you poo-poo it. You probably won't need to since you have what may be one of the best desktop scanners around even though its old. Go get a 3-5 year old flatbed (or an older film scanner) that does not work very well by todays standards, try it in both grayscale and RGB then come back and let us know how it worked. You might be surprised. As to using PS to do a grayscale conversion after scanning a B&W neg as rgb, it does not make for a better conversion. There is no color info to "mix" for better results. Before you rip into my posts why not suggest YOUR better method of work and tell why its better? Be positive and uplifting my boy! Tell how you do it. You probably have a smart trick or two figured out - that might help someone. No more from me on this subject. Henry - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
