A kind relative sent me an SX-70 camera some time ago, hoping that I could put it to some good use. Alas, the camera was not working, and it took me some time to find a repair person who was responsive. I finally found Chris Levitan, who rehabilitates Polaroid cameras out in Oregon, and when checked out the old camera he discovered she had been dropped at one point, and now was good only for parts. However, he was kind enough to offer me parts credit toward the purchase of one of his reconditioned cameras, which arrived a few days ago. He does excellent work and I'd encourage you to contact him if you're in the market for a Polaroid camera.
For those of you that are unaware, after the demise of Polaroid as an instant film company, a plucky start up venture purchased some of the factory equipment and re-engineered functional "Polaroid" instant film. Alas, its somewhat pricey, and they continue to iron out some kinks in the complex alchemy that makes these prints work, but it is an awful lot of fun and really nice work can be done using their stock. So far I've learned a number of ways to screw up with this kit (temperature, flare, exposure compensation, bad use of flash), but I think I'll be able to work through the learning curve. Ultimately, there is still a magic to shooting instant film, and I'm thrilled that it is available and continuing to improve.
