Some of the negatives are over 60 Years old and of varying formats. And considering their are thousands of negatives a scanner is to slow. This is a problem for the Nikon film scanner I have access to as it uses a cage to hold film. I have put it in the cage, insert it, slide it to desired position, preview it, scan it, colour correct. And finally I’m done.

Doing this with this setup would mean I don’t have to save and colour correction needed is minimal. And I can store as fast as i can advance the film. What was 3 minutes a photo is down to 10 seconds.

Good job, Thanks for the idea

If your slides top out, quality wise, at 1200 dpi then that is more likely an artifact of the lens used to make the slides than the slides themselves. Old Pentax lens, for example, typically top out around there. It would be difficult to find a lens from the 50′s or 60′s that would do better.

Most people already have all the parts, the slide projector which is kinda a prerequisite for slide owners anyway.

I have a scanner with a back light for scanning slides, so I would have rather built some kind of Slide ADF for that.

I also assume the resolution of digital cameras will increase, so this approach could have some kind of future proofing(assuming the slides last that long)

very cool hack, though Rondeau!

Still, a good slide scanner is going to work 100 times better than a rupe-goldberg dSLR setup.

I’d rather do it that way instead of building the rube-goldberg setup that does not do any better or give you any better “scans”.

hell get a film scanner for $125 and call it done at Costco. 1200dpi is way higher res than your 35mm slides.

a nice simple serial interface could fix that im sure, would defiantly allow you to go out for a few hours and still get through a few more. If it stuffs up at some point you still have not lost anything

great work indeed, cant wait to try it on my grandads collection
