I picked up a few Recesky TLR (film) DIY kits and just started working with it. It definitely has it's challenges. I started as a film shooter with an SLR so film is not totally foreign to me, but this takes some practice.
For one thing, the shutter speed is fixed, approximately 1/125, and the aperture is either f/11 or about f/6, depending whether or not you use a plastic piece between the lens and it's bracket. The main variable then becomes ISO. I used a roll of ISO 800 film for testing.
Here are some of my photos with the camera:
1. Double Exposure
It feels a little like a real life Instagram camera.
If you haven't tried one of these yet, I highly recommend you do.
