Hello, gang.

I've been trying to track down the source of an odd flare I've been getting. It is about the same every time but I can't find the cause. I think it's a problem with my calumet 6x7 roll film back. Here are some shots:



Now, here is a shot of one of the last two but on my Polaroid 405 back on FP-3000B

These seem to be devoid of the same kind of problem. It's such an odd effect I can't seem to track it down. This has happened across a few rolls of film. At first I thought it was a strange lens flare so I got a hood for my lens but the problem persists and I've never seen lens flare look quite like that. It only seems to happen when I'm shooting on a sunny day. To me, that eliminates reflections internally because light is being focused inside regardless of outside conditions. I double checked light leaks in the bellows, but if it were that it would be on all my pictures. I don't have a very wide selection of photos since I'm fairly new, but any advice would be appreciated!
