I guess both because the 35mm has settings for the film also. The Diana one tells which settings work for what.Good luck :).

I had never used a camera by having to use the focus or the fstop, so it was really hard for me. I just paid attention to what the book said and then my pictures came out. If you follow what the book says you should be fine. Also be careful with indoor shots because they don't work without a flash. I am getting one this Friday finally. Feel free to stop by anytime :).

Awesome! The Diana Dreamer was the one that got me into lomography. I mostly use the 35mm film. The first film I used was 120. It was kind of difficult to figure out, but I'm trying it out again now that I know how to use the 35mm film.

It takes a lot of research to try and find one if you don't live by a big city. It's best to explore where you live and ask around at places that take professional pictures and ask them if they develop 120 film. I have a Diana also and that was the most difficult part. Good luck :) I hope this helped you.
