Right, of course. I was just responding and sorting out the relationship to the much touted max screen res of 72 (or 100) dpi. I think I used to think that meant higher resolutions offerered no advantages becuase you couldn't see detail below that level, but now I see it relates mostly to size. I'm still not entirely sure why high res scans look better on a screen only capable of displaying 72dpi. I tried a slide at 2720 and then 680 dpi, sized the two scans the same, and the 2720 looked far better, especially under high zooms. Ken
