| Chiming in late---but I have had some luck taking stills from old super-8 films without cutting them up. This is a subject near and dear to my heart, since mostly what I have left of my childhood is on 49 short rolls of super-8.
My current scanner is a four-year-old Microtek X6, $89 special, with a "LightLid". I also have a moldy-oldy 8mm editing setup, the old hand-driven one with reels on both sides, and it was easy to set it up to where I could load a reel into the editor, roll it to the still I wanted, and then carefully remove it from the editor and stretch it up to the scanner. No cutting or splicing, but cleanliness is all-important, as is keeping cats etc. out of the way during the process.
As a caveat, I didn't get the kind of resolution being discussed here out of my X6, but the stills were still useable. I had no idea what I was doing at the time---this site hadn't yet been invented! I want to re-scan using the same technique as soon as I acquire a decent scanner, my old X6 is finally showing blurry, noisy scans with lime-green and magenta vertical lines from bad CCD pixels. (Or perhaps I'm just more picky these days?)
8mm is about 1/3 of an inch. With a 2400dpi scanner with a lighted lid, e.g. the Epson Perfection 2450, 600x800 (or so) is eminently possible, not much but probably good for a 3x4 print at 200dpi. Better than I would have expected with less than $500 in materials. A 4000-dpi film scanner will get you into the 5x7 category. Better than that will require cutting it up and outsourcing to a drum ($$$).
Also, I had this discussion on photo.net a while back, and I notice there are a few more threads. If you go hunting, also look at the threads on scanning 110 film, since it's very similar in size.
Someone displayed onto a screen and photographed the result with slide film, but was unhappy with the results. One suggestion was to simply mount 110 film in a standard 2x2 mount and scan it, I don't know why that wouldn't work for 8mm if you were willing to snip it. I would worry that it would fall down inside the scanner if using one with motorized feed.
(BTW, since 8mm film moves at 24 frames per second you can snip out a good chunk without actually disturbing the action to any great degree. Snip 3 consecutive frames, that's 1/8 of a second, faster than my eye can grab. Stitch back together and no one will be the wiser except grandma, of course.)
Let us know what you figure out! |
