Well, let's be more specific about this - scanning a B&W neg in RGB looks the same as scanning it in IR. It's *not* simply black in IR. I haven't looked at the comparison in detail to see if there's any minor differences like focus or contrast. > OTOH, it seems like it would create a perfect "mask" if > the neg were scratched, because the IR *would* pass > through the scratches. No. See above. An area of pure white on the neg (black in the original scene) will pass IR just as effectively as a scratch. So as I said earlier, you can't tell what is image and what is a scratch. The "scratch" could be real detail like a fine wire across bright sky. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
