First try with my new Diana F+

I don't really know why they are underexposed, i'm not use to the fixed shutter at 1/60.
Anyway most of them were black but those are the few which weren't. Some of them have interesting results and some have a black line on the left or right and I don't what is it.
I shot at a 12 square format and i didn't use any of the frame that came with the camera. Maybe I should have, please let me know :)
