[rollei_list] Re: What is causing this?

How fresh are your chemicals? How clean are your reels, your tank? If it's not the camera, it has to be the processing, particularly if problem persists over a variety of different films? How filtered is your water? Do you use photoflo? Are you getting contamination from that?

dust had settled on it before I took the picture.  FWIW, both rolls of
Fomapan which I shot with this camera had the apparent scratch marks on the 
negatives.
I have inspected the interior of the camera and can see nothing which would scratch the film nor do I see anyplace where the dust might be coming from.

My first thought was dust as well. Do other films come out differently
when you process them? I assume they do. You wouldn't ask otherwise. A
friend had a similar problem. I'll write him and see what his problem
was.
