This thread is for posting tidbits that you've learned about your camera, your process or photography in general. They might be helpful to others but the don't have to be. The only rule is that you have to have learned it recently.
I'll go first. I learned today that fixer CAN be exhausted! Obvious, right? The trouble is, when it is exhausted, it shows itself in subtle ways... weird posterization in the scan, slightly foggy negatives. Not always noticeable. That's why it's a good idea to keep track of how many rolls you processed with a bottle of fixer.
Man, what have i not learned? It seems I re-learn things everyday. I have learned a lot about film recently. (thanks to a lot of people in this group...) Ive been trying 35mm out. So far i think the photos are coming out ok. Basically i'm shooting with film to help train my eye to see before pushing the shutter button. Ive never been the person to just snap off photos and hope for the best, but I still have a lot of room to improve. And, film is teaching me patience. Something I have never had.
