Just got a great EOS 3 last week and am having fun playing. Quick question regarding leaving the leader out when doing a mid roll rewind: How do you folks work with that? Do you mark the canister with the last frame counted? What do you do when you reload that film? Lens covered, fire frames until the number you marked on the canister? I don't think this is a tough question but didn't want to waste film/frames experimenting with this one. Thanks for your help.
