I am curious about this, as since we have just opened and are trying to draw business. I have done one photo restoration job and just picked up a pretty huge slide/negative scanning job. It's a very complimentary thing to framing, as most would want their restored images framed nicely. I don't have the optimal setup for slide & negative scanning, so it's pretty labor intensive, but I've found that my old workhorse Epson v500 does the job quite nicely. I am able to give the client some decent resolution for later display or printing while still keeping the pace up in my workflow. At least the scanner does 4 slides or 10 35mm negative frames at a time .
