The largest you can scan with the wet mount adapter and the better lens is about 5" in width. 8 x 10 usually goes on the scanner glass. I think practically you'll get 1300 DPI or so for 8 x 10.

When scanning color prints at scan resolutions above 300 dpi, then, it follows that you are scanning not for detail but for size---you are essentially upsampling via the scan rather than later via Photoshop or some other image editor. If you do not intend to enlarge the original, there is no point in scanning above 300 dpi and you ought not to do so to avoid needlessly large files. If you do enlarge after scanning at 300 dpi, upsampling will give as good a result as having scanned at a higher resolution.

If the scanner is lined up so scanner-pixel 1 hits print-pixel 1 dead on, you are perfectly lined up and the scan is as good as the original.
If the scanner and photo are off just 1/100 of a pixel (!?!) then scanner pixel 1 gets pixel 1 and a shade of pixel 2. If pixel one is pure white (255,255,255) and pixel 2 is black (0,0,0) then the scanned pixel is something like (200,200,200)(mean, average, etc.) which means you lost the original pure white.

I'd say, for 8x10 with the worse lens, some 1500 to 1800, depending on the axis. The better lens scans 5.9", enough for two 120 strips on holder or four 35mm strips...Originally Posted by Jim Andrada
The better lens with a native 6400 dpi delivers some 2300 to 2800 (best of 5 results) optical performance, also depending on the axis.
