Black circles..

[ori_s]

Hi,
Any ideas what's making these black circles on the top of the frame?
I've been told that it can be lens separation but don't see something too scary on the elements.
Thanks

Looks like surge marks from developing. Too sharp to be a lens issue.

If it is roll film, it might be fogging from light piping in. Some details (camera, film, etc) helps.

Like Vaughn said, looks like a processing issue. Is this roll film or sheet film, and what's your developing process like? Tray, tanks, reels, etc, etc?
Looks like The streaking could be an agitation issue, as well as a problem with bubbles during development.

It's a linhof 612 with 135mm lens.
Film developed in a lab that i never had problems with before, not sure about their developing process.

Looks like too little chemicals in the tank or at the top of the tank surging, foam, or similar processing error. The dark spots are likely from over development in those areas. Refixing the negatives may reduce the spots.

Since the marks are in different locations on each frame it cannot be the camera or the lens. If they were in the same location then it could be the camera or lens.
That means it is film or lab. If the film loaded up on the side of the take up the film could have been damaged but it seems more likely to be a lab issue. Have you asked them?

Classic for bubbles. Patterson reels?

The dark spots are likely from over development in those areas.

Actually, as the image is a positive, the dark spots would be from under-development in those areas.
Most likely from bubbles and/or too little developer in the tank and/or reels that have moved up too high in the tank.

Air bells.

Not enough developer in the tank

 

[Ian Grant]

Definitely air bells, they can be a huge problem with some developers in hard water areas. Shouldn't happen at a commercial lab though.

Yup. Bubbles get trapped between the film and the reel on a lot of plastic reels. I changed over to steel reels with 120 film for this reason. Drove me nuts! Even whacking the crap out of the tank on the counter didn't solve it at times. Same with LFN. Too bad it happened to you when you were paying someone. You should let them know.
