    Weird glare on my prints

    I was printing today and I noticed I was getting a weird glare on my prints. It actually is two going across the picture. They are pretty uniform. I checked everything around the enlarger and the enlarger itself to see if I had a light leak or something. I even changed the lens which changed the height of the enlarger and I still got it. This is a brand new box of paper. Could this be a defect in the paper? Any ideas would be helpful. I have quit for the night, will try again tommorrow. Decided to break out some wine before I break something else.

    If you suspect that it is a defect in the paper, try exposing the paper in a different orientation and see if the orientation of the glare changes position. If not, then that would point to something at exposure time.

    My guess would be that you're getting a reflection off some other surface in the darkroom - perhaps an enlarger leak that's bouncing back and reflecting off the column. I'd suggest tracking it down by using a piece of black paper or cardboard to block the easel area from various positions and angles, then work back from there to the source.

    If it were a reflection would it be white or black? These marks are white.

    That depends on where/when you're seeing them. If under the enlarger, a reflection would appear brighter (whiter). If in the developed print, a reflection would show up as a darker area. Whiter/lighter areas in the processed print would point to either a disruption of the light path, a fault in the negative, or (least likely) a fault in the paper.

    OK, Kevin, this has got to be easy to sort out on your own. We'll just be talking endlessly here without anything to see. If you are seeing white streaks on your developed print and it were an enlarging fault, you would see dark streaks on the projected negative (we are talking B&W here, right? You haven't really given much information.)

    Do this: 1. Under safelight, remove one sheet of your paper. Put the rest back into your paper safe. 2. Turn on the room lights. 3. Develop this sheet of paper under the room lights. If the paper ends up with those white streaks, you either have bad paper or something wrong with your development process.

    Beyond that, I think you have to make an effort to debug this yourself.

    Ok, I think rbarker has got it. It seems to be a disruption in the light path. After messing with the paper and stuff that was around the enlarger, I printed a shot at about the 4x6 size. Up until then everything was around the 8x10 size. The marks were there at the 4x6 and proportional to the smaller size. I am not seeing anything in the path though. Would this possibly indicate needing a new bulb? I'm going to take it apart again, but was just wondering since this is my first enlarger.


    Looks like the bulbs okay. Tore it apart again and cleaned the elements, I don't seem to be getting the lines now. Sorry to bug you guys on this, the prints where for my final project in a class, and the deadline was coming up quick. Started to feel the pressure. First time I've had this kind of problem, so wasn't sure where to start.

    I spoke too soon. Thought maybe the elements where misaligned after cleaning everything. I am still getting them. The only constant I can think of now is the bulb. Has anyone had a problem with a bulb sending strange shadows through the light path. I know this is a reach, but the enlarger isn't that complicated (omega c700) and I'm running out of ideas. If I can get a print scanned I will post it.

    How heavy is the "glare"? Is the image under the glare (on the print) completely absent, or just lighter than the surrounding image? When you look at the negative image projected under the enlarger, do you actually see dark streaks?

    If you project a clear (unexposed) negative, do you see these streaks? If you have no negative in the carrier do you see these streaks?

    That's whats confusing me. I cannot see these on the projected image. I did this with and without the neg, both enlarged as big as it will go and small as it will go. Its fairly light on the print. Most noticable when I bump the contrast up on the image. A few of the prints I was working on I was going for a heavy contrast. I did take the filter out and overexposed a print to see if it might be the filter but it appeared again.

    I am down to the bulb or the heat absorbing glass I guess.
