Title: Scanning stereoscopic slides
Post by: terrywyse on March 01, 2015, 11:30:10 pm
Hello all,

My parents just went through thousands of stereo slides and wittled it down to mere hundreds.....and since I'm the scanning "guru" in the family, I've been tasked with converting these to digital images.

I have both an Epson V750 Pro and a Screen 1045ai drum scanner. Obviously (or not) I'd rather not have to unmount hundreds of slides from their paper mounts so the drum scanner is out. What options are out there for scanning stereo slides in their mounts?.....or should I just bag it and hire a scanning service to relieve me of this burden? :-)

I would consider purchasing a dedicated film/slide scanner as I have more than a few standard 35mm mounted slides of my own......but I don't want to get the slide scanner only to find out I'll still need to unmount all the stereo slides.

Ideas?

Terry

How about building a jig to hold the slides in place and simply photograph them with a DSLR and macro lens. We copied a few thousand glass mounted slides this way using a D800 and 60mm Nikkor macro. F/11 was used to have enough DOF. It took an average of 30 seconds per slide to do the copying, and another 30 seconds per file to adjust colors and crop in Lightroom. Much. much faster than scanning and the quality is more than good enough (actually better than the Nikon scanner I have).

There is a LuLa article here  (http://luminous-landscape.com/scannerless-digital-capture-and-processing-of-negative-film-photographs/)on scannerless  digital capture which might give you some ideas.

Cheers,

Hi Terry,

Yes, digitizing them with a camera is a clear option. The other thing you could do is use SilverFast that came with your Epson V750 in batch scan mode. You can deploy SilverFast's "Find Frames" tool to isolate the material that needs to be scanned and then scan them in batches as large as the number of those slides you can fit on the platen. I would test this using the Epson fluid mount assembly without actually removing the media from their mounts. You can buy this FMA from the Epson store for about 60 bucks. It is a glass platform that has the right displacement from the scanner bed for unmounted media. However, there may well be enough DOF in the scanner to accommodate the mount if it is thin. Give it a try, because if it works well, it's an efficient approach.
