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?

I think that I can eliminate processing as a factor since I have severalother medium format cameras which I use regularly. I had thought thatperhaps the camera was scratching the film but when I shoot Tri-X I do not see these scratches. Instead I get the black specks on the film, as thoughdust had settled on it before I took the picture. FWIW, both rolls ofFomapan which I shot with this camera had the apparent scratch marks on thenegatives.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.- Peter Schauss-----Original Message----- From: rollei_list-bounce@xxxxxxxxxxxxx [mailto:rollei_list- bounce@xxxxxxxxxxxxx] On Behalf Of Douglas Nygren Sent: Sunday, February 25, 2007 8:33 PM To: rollei_list@xxxxxxxxxxxxx Subject: [rollei_list] Re: What is causing this? 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.
