Horizontal Lines in prints
I seem to be having a very annoying problem with my 35mm cameras lately. I am getting a number of very very fine horizontal lines going through the print (from the negative of course). The lines extend from one end to the other and are perfectly straight. They are white in color(black in the negatives) and sometimes there's one...sometimes more. Could it be that my shutter curtain is leaking light? Has anyone else experienced this, or have an idea of what it could be? The crazy thing is that it only shows up with B&W film. I ran about 3 rolls of color through it, and there was nothing to speak of. Thanks.
Spot using that inktjet NOW!
Sorry, could not leave this one go :-)
Are the lines always on the same spot of the negatives?
The first thing I could think about is dust in your camera back.
I had similar problems some years ago with one F80, the problem was with the pressure plate.

Do you process your own film or send it out?
as stated could be pressure plate,
could be dust in the camera
if your film is being sent out the cause could be at the proofing stage, poor handling .
if your film is being sent out , and the lab uses a roller transport film machine for the black and white this also could be the source.
If you are processing yourself and are not photoflowing correctly I have seen a white line in the print that runs the lenght of the film in the last few frames.
If you send to a lab , check what type of machine .
If you process yourself then I suspect the camera.

I process my own B&W...I send out for color. All B&W film gets a final rinse in DI water with photo-flo. I'll take the camera in for inspection....I'll also try a new wetting agent.
Do you bulk load your B&W film?

wouldnt a scratch on the base side of the film produce a white or light colored scratch on the print? If that is the case then I suspect the aforementioned pressure plate.
