Since the scanner moves so slowly, I can expose each frame as many times as I want before advancing. I also started using a 9-LED array as a light source, which led (pun!) to an interesting experiment. I've also filed out my gate a bit, although I'm not quite finished with that yet. I've upgraded the optics to a Schneider Componon 80mm enlarger lens, which is worlds better than the repurposed medium format lens I was using before. That does some of the best scans I've seen.Īnd since there's some interest in this thing after all, I thought I'd share some little updates. I'd recommend checking out the Muller HM film scanner for inspiration. Peter, I'm definitely getting more than HD as far as image size goes (vertical resolution anyway), so it's certainly possible. I'll keep that in mind as I continue to experiment with negative color stocks. Hey guys, thanks so much for the comments!ĭavid, I think that's a really good idea. I expect good things!Īnd yes! 16mm! Absolutely! I just got a Beaulieu r16, so that's definitely on my list of to-do's. Anyway, I'm going to try and shoot some 50D next week and see how that does. I really didn't expect it to work at all, and then this stuff started coming up on my computer. Here's an un-corrected frame, just a straight inversion: I was really surprised the color negative stuff came out as well as it did. Could get some ludicrous resolutions that way too.

I'm not sure about DSLRs, but even if they didn't work in OpenCV, the code could probably be modified to capture a frame some other way. The built in iSight even opens, so theoretically that's even a possibility. It'll definitely work with any camera that works in OpenCV, so far I've tested my machine vision camera, and an HDV camera, and both of those open up no problem. The added bonus is that it should work with almost any camera. I didn't realize how slow it would be at the time, but at least it works! So I figured it was better to go the stepper motor route. It definitely scanned fast, but it was inaccurate and jittery, and sometimes it would capture the pulldown. I started off using the projector's original motor slowed down as far as it would go and still turn everything, and I was using a modified mouse button to register frames.

It's this motor, plus EasyDriver and Arduino Uno. So here's a demo video showing how it works.
But like I said, I'm still working on it! It runs autonomously, just set it and forget it. I'm still not set on the optics, but currently I'm using a medium format camera lens reversed on a sort of macro rig.

The software is written in Python, and I'm running it in OSX (10.8.3, if you're curious). The camera is connected via Firewire using libdc1394 and OpenCV. The camera is a Sony XCD U100CR color machine vision camera capable of 1200x1600 pixels. It uses an old Dejur Super 8 projector, which is run with a stepper motor and an Arduino. So I've been working on a DIY film scanner and I've got it working somewhat well, so I thought I would share it here just to see if anyone else is interested.
