When I first got my Zorki, I was up to about 1 roll per week, for a month. That was near my holiday average of 3-4 rolls per week. Now I'm back down to basically nothing. When I get my iiic back this week & I finish my exams in 3 weeks, I'll be more active again 🙂
I don't have a room that I can darken without making lots and lots of dust (blankets in front of the door etc.) so I just dump them at the lab. I don't care too much anyway, it's what ends up on my film that needs work, not the post-processing.
