When I returned from Paris this summer I developed all my film except one roll of black and white 120, because the place I drop my film off cost extra to do black and white. Since I'm cheap, I decided to do it myself. I forgot what was on this roll, and it sat in my apartment for a 5 months. When I had a chance to develop it, I had no idea what was on it. I was so happy with the results.
I used my Yashica A, which has no meter and sometimes doesn't work very well, so I was pumped that they all turned out.
