Chinon CS: Blank Roll

Darryl Roberts · Jun 2, 2024

Hi,

I recently acquired a Chinon CS and the result of the first roll from the lab say “blank roll”

I recall the film wound on to number one. At the end of the 36 shots I recall the camera allowed me to keep shooting before i realized it and rewound the film.

Please help with any advice

Thank you

I know very well basic photography. I successfully shoot medium and large format photography.

Is it possible that the film slipped off of the takeup spool in the camera?
The camera's frame counter doesn't care if the actual film advances or not.
When rewinding the film after shooting a full roll, it should take a dozen or so turns of the rewind knob before you hear the film disengage from the takeup spool.
I'd suggest loading a junk 'test' roll in the camera, taking up the slack, and watching the rewind knob move when advancing the film....no rotation of the rewind knob = no film advance.
I once had a roll of 35mm film break shortly after the leader...I ended up taking 36 exposures on one frame of film.
It only took one turn of the rewind knob to hear the film go back into the cassette.
If I had paid attention to the rewind knob when loading or photographing, I could have done something about it.

That's what I expect, yes.

Always make sure the rewind knob turns as you advance the film after closing the back.

I believe the same thing others have said. The film slipped off the take up spool. To prevent that check the rewind crank and make sure it turns when you advance the film. Also try to rewind without pushing the rewind button. You should not be able to rewind if you don't push the rewind button. If you can than the film has slipped off the take up spool.

An almost "fool-proof" solution. Try this method -- if nothing else, to determine if you are, in fact, a "fool". If you messed up the film loading, this approach can quickly and easily pull the leader all the way into the film cassette -- making it useless.

Fool me once,....

It's easy for me to pull the leader backout of the cassette with a leader retriever. And today it's difficult if you don't have one. Back in the days you can go into somewhere they process film on site and they can pull it out for you free. I've done that so many times for people when I was managing a 1 hour photo shop.

I've got a leader retriever, but I doubt the OP does. Anyway, I know how to rewind the film leaving the leader sticking out. I doubt the OP knows how to do that too!

This happened to me a few years ago when I got my first Nikonos. With that camera two things:
1) the rewind knob is disengaged when pushed down, so it is not easy to detect if the film is moving when winding
2) the rewind knob, when pulled up to rewind, is stiff from the o-rings. So it is not easy to detect if the film is being wound up. In most other cameras it is pretty obvious when the film did not advance because one can feel it come off the spool in a few turns or less.

So I actually processed a blank roll! Now I'm real careful with the Nikonos to see the film advance a frame or two before I fold up the pressure plate.

Thank you all very much. I shot another roll and "To be certain that the film transports correctly, take up any film slack in the cassette by turning the re-wind crank clockwise till resistance is felt. When advancing the film the rewind knob should turn counterclockwise. This is evidence that the film is loaded correctly. "

Not only was the rewind knob turning counterclockwise, this time when I reached 36 it wouldn't go further.
