Thread: Black prints

    Black prints

    I'm new to printing and the problem I'm having is that when I try to print a neg ative, the enlarging paper turns black. Doesn't matter if I use one second or 2 5, I can't get a test print. I'm using an old C700 Super Chromega 6x7 Dichroic enlarger. I expose the paper (Adorama pearl) and put it into the developer (Dek tol 2:1) and within seconds it turns black. What am I doing wrong?

    I don't know. I would try to put a piece of paper in the developer without any exposure and make sure that it is nice and white after it goes thru the stop and fix. If it is not bright white then it is the paper, chemicals or darkroom. If it is nice and white then it is light leaking from your enlarger, or too much exposure. Start there. Have fun!!

    Just a thought, did you try stopping down your enlarging lens? Maybe you have it open too wide, thus over-exposing the paper.

    Dektol 2:1? Did you mean 1:2 or did you really mix two parts stock solution to one part water? Normally it's the other way around (1 part Dektol, two parts water).

    Taking every response in turn: 1) Yes, it was Dektol 1:2, sorry I wrote it wrong. 2) The lens was at f8. 3) Developed an unexposed sheet and it turned out bright white, but if I use ANY exposure, even a second or two, the paper turns black. 4) I tried turning off the safelight, sealing off any light leaks in the room, checking to see if the right side of the paper was up (that was an adventure: Printed on the backside of the paper, the image came through on the correct side overexposed). Will try to seal off any light leaking from around the bellows and/or negative carrier. When does the fun begin? Or is this the fun?

    Hi Richard, I've been using the Adorama for quite a while, mostly for contact prints and for getting the various exposure and contrast filter selection correct. I've found the paper to be very fast and for contact sheets I've had to stop the lens way down. If you are using the dichroic head are you dialing in some degree of filtration? If not try adding some - it usually reduces the light enough to make useable prints. It may bee that your light source is very bright & you may have to figure out how to add some neutral density. Good luck. Eric Lohse

    If everything is black, I would stop down to f16 and try that. Also, make sure you have the correct bulb in the head. Just another thought...

    Definitely stop down the lens. If that doesn't work the C760 dichroics have some (three, I believe) drop-in diffusers which will also help block some light for extremely fast papers. Question: is your negative excessively thin? Have you tried to print more than just the one?

    Hi Richard,

    Check the lens. Take it out and look through it while stopping down or up. It could be the lens get stuck in the between but showing full down. How high or how low your enlarger was raised?. Aprox. height for testing should be at eye level.

    What temperature is your developer? Make sure is is 68 to 70 F. To slow the process down, you could try even colder. Maybe 62 to 68. Hydroquinone looses it effectiveness as temperature goes down.

    You could also try an even more dilute deveoper solution. Try 4 parts water to 1 part Dektol stock. Normally you would have to increase your development time to compensate.
