C2N holder is fogging

greenspun.com : LUSENET : Large format photography : One Thread

My Calumet C2N roll film holder is partially fogging some frames - i suspect based on tests that the dark slide lets in a bit of light cause if i take a series of shots with the holder in place, only the first is fogged and subsequent shots are fine. Is this a quirk of the holder, my particular holder or what? The dark slide has an inward notch on it and doesnt slide under the frame very much. Should the dark slide have a square end on it? (ie. is the dark slide an incorrect replacement?)

Thanks all,

I have an older C2 holder and the dark slide is indeed notched as you indicate. One suggestion though, you might want to ensure your holder is seated fully in the camera. When I used the C2 on certain cameras it really took considerable effort to ensure it was fully seated and on one camera the ground glass was incapable of fully closing on the back of the holder.
