Polaroid Help!

[useless generation]

Hey guys I bought a custom Polaroid Land Camera not long ago and I've noticed the same white mark in a lot of photos. It's from both FP-100c and FP-3000B films and I'm not sure why. I constantly keep the rollers clean.

Looks like a light leak. Take the camera in a dark room open the back and shine a light into the bellows. You should be able to see where the leak is. The time between shots probably affects the intensity of the mark. If you just bought the camera from a custom shop, they should replace the bellows for you.

Thanks for the input I've tried that already and I can't spot a leak. The only thing I can think of is a slow leak through the shutter at the front? I loaded a new roll and the shots I took turned out but I left the camera for around an hour and just pulled the next shot out and I got this

Try taking a few shots with a dark cloth over the bellows. If they come out o.k. then it will be definitely a silt on it. It could be on one of its folding edges, and this is why it is hard to be spotted.

I had a light leak with an Automatic 100. It was not from the corners of the bellows, it was from the area on the bottom of the bellows where the material is sealed together. I re-glued it with black silicon adhesive. I couldn't see this opening with the normal flashlight in the camera.

I've had the same problem as John, with the same fix. That Fuji FP3000b film is so sensitive that even the most microscopic leak shows up.

We have an interesting effect when we leave Polaroid pack film cameras on display in our shop with FP-3000 film loaded in them. If there is a tiny hole in the bellows, it acts like a pinhole camera! It took us a while to figure out why we were getting these cockeyed double exposures....
