I'm fairly new to this. A few months ago I picked up a Stereo Realist 45 (35mm). I used it once just to test - using color negative film, I scanned the negatives, put the pairs together (for cross-eyed viewing) in The GIMP, and had them wet-printed at Walgreen's. I didn't assemble the images well, but the camera works perfectly.

Next week on vacation I'll be using it "for real." I'll use transparency to do it the right way, and probably some B&W negative film so I can optically print them when I have the bathroom set up as a darkroom.
