Hey gays is my first post on the website and I'm pretty sure it won't be my last, I have gained some success locally with my digital photography work but I have a photography assignment next September and I'd like to have it all 35mm film photography. I have a Zenit the camera feels really nice in the hand ridiculously heavy I'd like to use the camera for as long as it can live. I replaced the battery's for the late metres but they stop working now I was reading that their useless anyway. The film I have is 400 iso on the Zenit I've got ASA-16-32-65-130-250-500 if someone could explain what I should set to there are also gaps in between those intervals. I look forward to growing knowledge with you gays!
