Subject: [rollei_list] What is causing this?
I have run three rolls of film through my newly acquired Rolleicord Va and 
all seem to have a problem as shown in the link below.

When I use Fomapan 200 (developed in Rodinal) I get a whole flock of short vertical lines on the print. These are especially noticeable when the print is highly magnified. With Tri-X (developed in HC110) I get black specs 
which are you can see in the sky areas of the prints.
I suspect that both of these problems are caused by dust which falls on the film from someplace inside of the camera since I have had similar problems with the black specs when using a folder like a Moskva. In this case, however, I do not see any obvious places inside of the camera which could be sources for the dust. The interior of the camera looks quite clean.
Any ideas where the dust, if that is what I am seeing, could be coming from? 

Thanks,
Peter Schauss
Check the steaks and spots to see if they are mechanical damage to the film, especially the back side. A magnifying glass and light shown obliquely across the film will help. The dots may be from pin holes. These are probably caused in processing in some way. Its curious that the blemishes show up only in about the top third of each frame unless they are masked by the image elswhere and are actually everywhere. 
   How is this film processed?
