    Calumet C1 question

    I own a C1 and am having problems with my 8x10 back leaking a bit of light around the film holder. My model has a bit of felt on the fixed section of the back that the film holder rests against. It looks like this felt was added to the camera. My 4x5 back for this camera is similar, has no felt and doesn't leak.

    My question: Is the 8x10 back supposed to have felt or should the film holder sit against the metal?

    Thanks. Shawn

    You are putting it in on the wrong side. I did the same thing with my c1.

    Shawn,

    I too have a C-1. Mine has a thin layer of felt in a recessed grove that runs the perimeter of the back. I've never experienced a problem. The felt is thin and does not protrude above the surface of the back. However, I have a B&J 5x7 which has no felt strip and I have never had an problem with it either.

    Don't feel bad. Me too. Took me two sessions and ten sheets of HP5 to figure this out.

    I'm not sure I understand... Do you mean the felt should be on the part of the back with the glass? The groove should be empty and the felt should touch the back of the filmholder? Thanks. Shawn

    Hmmm. I have a B&J 4x5 that does have felt in the recessed grooves you described for your C-1. The grooves (and felt) are on the back section with the GG.

    I'll take a look at my C1 when I get home, but I don't recall it having any felt on the 8x10 back anywhere.

    Hi, it does have felt. I think maybe some are thinking you are inserting the film holder from the wrong end, and that the ridge of the film holder is not seating in the slot?

    Thanks everybody.

    No, I am not inserting the film holder incorrectly. The ridge on the film holder fits nicely into the slot, it's actually the other end where I am having the light problem. I was trying to find a consensus reguarding felt or no felt... I'm thinking of removing the felt entirely and exposing a few sheets. Any further recomendations are appreciated. Thanks. Shawn

    You should be able to test for leaks with a bright flashlight inside the camera in the darkroom. Save the film.
