    Trouble with TRI-X and TMax developing

    Hello.

    I'm in trouble with Kodak Professional TRI-X 400 (400TX) film and Kodak T-MAX developer.

    As i can read into the film box, the times at 20║C are 6 Minutes + 1/4 minute, but when I develop the film (with already used developer) in a small tank the base of the film is dark but the numbers and markings get gray, as if were erased.

    My questions are?

    Are the semi-erased numbers and markings a sympthom of overdeveloping?

    Can this be due to contaminated developer, light leakages, ...?

    Many thanks about your cooperation.

    If the base is black all the way to the edges I guess it has been exposed to light by mistake (the base should be clear at the edges as the film normally shouldn't be exposed there).

    Hello Morten.

    I'm having troubles with my english (spanish native)

    No, the base is not black. It's sort of an uniform gray and darker than another negatives i've developed before with success. The strange are the "overdeveloped" markings (I suppose)

    Of course, many thanks about your support.

    If the base is clear and the numbers are not as black as before it sounds like you did not develop the film as much. This could be because you reused the developer, or you used less time, or the temperature was lower. How is the image? If it is also lacking contrast you need to develop more.

    I agree with L.G. although I don't have experience with T-max developer.
    Sounds like your developer is no good/used up. How old is the developer or I should ask, when did you last use it before this problem? Some developers don't last long, are are usually meant for one use.
    You say the base of the film is grey, do you mean both edges are gray or just one edge?

    Hello.

    I was sure it was a sympthom of overdeveloping and you suggest it's about underdevelopping.

    Do you suggest the numbers get darker with mode developping?

    Do you know any place where I could read more about this?

    Many thanks.

    Yes. If you develop more the numbers will become darker (they are highlights) as the contrast becomes higher.

    Yes, the more you develop the darker everything will get. The rate it gets darker is related to how much exposure it was given.

    Do you know any place where I could read more about this?
    The Ansel Adams book "The Negative" is a good classic text to start with. Or just read through many of the posts here on APUG. A book is better for a novice I would say.

    'The Negative' is a pack of lies.
