Re: Film Scanner

I have an Epson V700 flatbed scanner, which has holders for 12 slides and 12 negatives.

This sounds ideal on paper but it isn't; the optical resolution of the scanner is only about 2300 DPI, and the focus adjustment for slides and negatives has limited resolution.

From this review

The claimed maximum resolution of 6400 dpi is higher than in most film scanners. But how much does the Epson Perfection V700 Photo really reach? In a test scan of an USAF test chart the horizontal lines of the element 5.3 and the vertical lines of the element 5.5 can yet still be differentiated. The result is therefore an actual resolution of only about 2300 dpi. That's less than 40% of the claimed resolution. The scan of a 35mm-slide or a negative using 2300 dpi, results in a file with approximately 7 megapixels. That's within the range of many common digital cameras.

The Epson V800 is very similar except that additonal glass surfaces add more CA. Review

Scanning the 12 slides or negatives takes nearly 40 minutes on a V700, and 30 minutes on a V800.
