    Hi again....as I found out I'm not supposed to use T-Max developer with T-Max 100 sheet film according to Kodak I'm wondering which developer to sue for T-Max 100 4x5 film....

    .......a friend suggested Ilford Perceptol.....was wondering if anyone's using this combination for 4x5 and could post the developing times they use for me at 20 and 21 degrees for example....

    or maybe some of you could suggest what THEY use with T-Max 100 4 x 5 sheet film...

    Kodak only recommend T-Max developer for 35mm and 120/220 film rolls. For sheet-films, T-Max RS is recommended. Perceptol is Ilford`s equivalent of Microdol-X, which is an extra fine-grain developer for which you will lose some effective film speed. Ilford provide a time for T-Max 100 in Perceptol diluted 1+1 for 13 minutes at 20*C/68*F. You may need to expose at E.I. 64-80 when using Perceptol.

    As fine as is the grain of 100TMX, especially since you're shooting in 4x5, a fine-grain developer seems unnecessary. Xtol or D76/ID-11 work beautifully with this film; and, judging by its look in roll-film size in TMAX developer, it would look great in TMAX-RS, since they are essentially the same developer.

    These days, my preference is D76. Love Xtol (and it is, or was, Kodak's recommended developer for TMAX films) but I'm trying to simplify and standardize down to one or two developers. The other will likely be TMAX, given its long shelf life and beautiful results.

    My understanding is that the dichroic fog problem with TMAX dev and sheet film is not an absolute; I've heard reports that Jobo users don't invariably see this problem. Any other thoughts on that---now that i've tried to hijack this thread? :smile:

    I have read that as well. I would also be interested to know how any 4x5, 8x10 etc sheet-film users find the standard T-Max developer when rotary processed compared to the RS version.

    Good Afternoon, Keith,

    I use only standard T-Max Developer with both roll and sheet T-Max films. (I had earlier posted that information in response to Sperera's question--or was that in a different thread?--but that post seems to be missing now, for some reason.) Anyway, I've never had anything but absolutely pristine sheet-film negatives when using standard T-Max; I use 1:7 from concentrate and process in a rotary drum on a motor base. A Search will locate some previous threads on this topic.

    Good Evening, Sperera,

    I can't think of any reason it would.
