I have access to a set of about a thousand 9 x 12 film and plate negatives from about a century ago. They belonged to a friend of my father's who died 38 years ago. He was a keen art and humanities amateur, musician and painter - I got to know him as a boy. A week ago I was able to browse part of the collection, which is stored in a couple of cartons. I am sure that there is material of historical interest there and want to do something to rescue it.

I would like to somehow digitalize the images, not necessarily with high quality, but good enough to organize the collection and to select those with special interest.  Problem: I have no access to scanners that can work with that size. My own flatbed will work with 6x9, but scanning and joining one thousand images takes more time than what I have for this project.

I was thinking of making a mask for my makeshift light table, setting a digicam on a tripod, photographing the negatives and then inverting. This should at least be quick and cheap enough.

Has anybody tried this? Should I consider another workflow?

The only alternative I could think of is contact printing, but it seems  too expensive and time consuming for a first screening.

All ideas and comments very welcome.

If you can set up a solid tripod and your lightbox is close to 'daylight', then using a digicam should be quite efficient.  The downside (of not having a better scanner, I guess) is that you might have to spend more time on adjusting the levels after you've done the shots.

Otherwise, with a good mask, stitching might be faster than you think.  Best thing is always try.  It certainly sounds intriguing.

If the digicam has enough megapixels, and focuses accurately, it might well produce quite adequate web-size images (or a little bigger than web size), though it won't begin to compete with the 88 megapixels I get from 9x12 cm with my 2400 ppi flatbed and glassless negative carriers.  OTOH, your digicam also won't take up your whole hard disk with the images -- 1000 scans at 88 megapixels would be a little over 90 gigabytes counting waste space...

I am aiming at producing images of, say, 600 x 900 pixels, low compression, for evaluation on a PC display and maybe to organize later in a Web site or CD. Images would be 8-bit grayscale. Therefore, Web quality is OK.

Need a cycle time of well below a minute per image in this initial register. I think I can achieve that with a tripod or support for the digicam and a mask over the light table, and reasonable workflow organization.

The big question is, will I achieve reasonable tonality etc without major postprocessing... This I have to answer by experiment, no other way unless someone already has done something similar.

Thanks for the comments; will post results here when I have something.

I sometimes copy book pages with my digicam, and my dad has duplicated hundreds of 35mm slides with good results. IMO, it's way faster than mucking about with a scanner, and the quality is plenty good enough for web or casual display use. OTOH, if you have some real treasures there, you might select a few and spend the time or money to do really good scans and make prints.

I expect you'll be pleasantly surprised.
