I recommend this camera if you're a patient and artistic person with an attention to detail. It might be a good idea to read a little about pinhole photography before you use it. It's kind of a trial and error process and it can be both rewarding and disappointing. I'm going to write about our experience with this camera. We had never done anything like it before so keep that in mind.
My boyfriend put this together and it took him about 2.5 hours. There's a lot of little pieces. We took 3 rolls of 24 exposure 200 speed film. It's hard to figure out how far to turn the knob to advance the film between photos (2 full turns?) so a lot of our pictures were smooshed together instead of being 24 seperate photos. I tried looking this problem up but I couldn't find any information on it so again, this is just our experience with it. It was very easy to take (deliberate) double exposures. I don't recommend 1 hour photo but if you do, tell them you're using an experimental pinhole camera and that a lot of the photos will be weird or blurry.
The camera comes with a cardboard tripod. It's necessary to hold the camera very still or your pictures will be blurry. There's an exposure chart on the camera itself which is pretty useful. You can expose it anywhere from 1 second in bright light (we averaged 3-5 seconds) to 30+ minutes in dim lighting. Taking pictures is easy. You just pull up on this cardboard piece to open the lens and then you push it back down. The longer you leave it open (as long as it's kept still) the clearer your picture will be, but it will also take on a red tint.
This was our first pinhole camera experience. There's a lot of trial and error involved if you don't know much about pinhole photography (which we didn't.) I recommend taking notes on what you did for each photo so if one comes out looking awesome then you can use that technique again and hopefully yield more awesome on your next try. Good luck!
