More than once I've tried to advance a 24 exp roll beyond that, thinking it was 36 exp roll. It doesn't work very well. Usually tears the sprocket holes, and I have to open the camera in the dark and fish things out.
If it makes the op feel any better, Ken McLeod says there are no problems or mistakes, there are only obstacles in the landscape that need to be negotiated. I like that, but believe he is mistaken.
Partly to blame is that the OM-1 doesn’t have a memo holder on the back to put the top of the film box in. I have since switched to an OM-2 back which does have the memo holder. On the F4 bodies I have been putting a post-it note on the back. Not a very elegant solution.
