Long scratch on film from Bessa-T

[nuckabean]

I picked up a Bessa-T at a camera show in seemingly perfect condition. I've enjoyed using it but I just got a roll of slides back and a few of the slides have what comes out as a cyan line going through the frame and you can see the physical scratch if you hold it up to the light. It's not very long, only shows up in a few shots and never fills the whole frame but it's annoying all the same. It's at the same height in every picture that it appears. What could be doing this? I had similar issues with the other roll I shot with this camera but I haven't checked the two together to see if the scratches are in the same place. Have I just had bad luck with processing both times? That seems unlikely even though I wish that was the case.

Here's a shot from the first roll where it appeared. It's not as drastic as the second one but if you enlarge it to "original" size you can see the scratch about 3/4 of the way down the frame.

Thanks all for your help!

If it is only one roll, I would try another before blaming the camera: it could be a bad film cassette, or the film scratched in development.

Is the scratch at the end of the roll? I had a problem with my Bessa L where a small grain in the take up area scratched the film. But only the last few frames.

I had the same problem on my R3A. I bought the camera used and the first roll came out scratched. i started to freak out, bought another roll, and never seen the problem since.

maybe we loaded the film wrong?

Well it was a large amount on my first roll, less on my 2nd roll, and my third roll has a scratch on like only one frame so I think I'm in the clear.

Since the "scratch" has a color cast I would check and clean the film scanner. One or two blocked pixels on a scanner can give a color line like that as it travels across the film. If there's dust in there, the "scratch" may come back.

Thanks max but they are visible on the actual slide with the naked eye.
