    T-Max 3200 processing time exp at 1600

    The Paterson Aculux says processing time of 16 mins for Tmax 3200.

    I have exposed this film at 1600 - do I reduce the processing time?

    Thanks,

    Matt

    The rough rule of thumb would be to reduce development time by about a quarter to a third for each stop. Try about 12 minutes.

    Never mind... in vino veritas not.

    Some find the true speed slower than 3200. I don't. But you could process as usual, saying the true speed is closer to 1600 than 3200.
    If you tone it down alot, it almost becomes bearable.

    Wouldn't exposing it at 1600 be overexposing it? You would be giving it twice the exposure that you would for 3200?

    Yes, of course. I had a champagne-induced brain cramp there before I edited... Sorry.

    That's okay. I was nearly about to agree with you before I had a proper think about it.

    I suppose a lot depends on the developer you're using, but a lot of people (me included) find that exposing it at 1600 and developing for 3200 works well. I've usually developed it with DD-X.
    If I had been present at the creation, I would have given some useful hints for the better arrangement of the Universe.

    OK, thanks for the replies everyone.

    I went with the first suggestion which was:

    Aculux for 12 minutes

    I presoaked the film and fixed it twice.

    The negs are sparkling and look really sharp!

    (apart from the last 10 shots on the roll which had a little vignetting which looks like a camera problem. I can easily crop it out during printing without changing the composition of the print as it is only small, but irritating none the less)

    Thanks for the help everyone!

    Phew, I'm glad my suggestion worked! I only said ABOUT 12 minutes, but if the negs are sparkling and sharp then, well done.

    No, Kevin, no no no! All wrong! This is where you post:

    "Hmm, yes, exactly as I have predicted. Hold my calls, I'll be on my mountain top!"

    That's what I would have done, heheehehehee - you are waaaay too modest!
