    The Problem with Xtol - Some After Thoughts

    I would Like to thank everyone for their responses to my earlier posting includi ng Kodak, who have advised me that this problem only exists / existed in the 1 l itre packaging. Thinking back about my experiences with the failures, I can't di spute this - nor can I confirm it. If so it solves a lot of problems for me.

    Anyway, I would like to share a couple of other observations - things that I thi nk I've noticed. First. Xtol is sensitive to agitation. I never had a problem wi th uneven development until I began to use Xtol. It required me to change my tec hnique and pay a little more attention. Easly to solve, but you have to be caref ul. Second. The developed film takes on a slight brown cast. It doesn't appear t o be neutral grey like in HC-110 or ID-11. Not a problem - just an observation. Last. Film base + fog is increased. There is noticeable density in the film edge s. Sometimes it's a little distracting but easily printed through. Since my last failure, I have used ID-11. The results are so reliable and the film looks so g ood, that I'm almost reluctant to give Xtol another try. The problem is that whe n it works, it can work beautifully. I'd welcome any discussion on my observatio ns.

    > developed film takes on a slight brown cast.

    I have found that the densities and colour associated with the emulsion in Xtol (brownish cast) benefit CCD scanning. I also find that developing times in Xtol are always 30% greater than Kodak's specifications, which remains a mystery. I am surprised that others have not seen the drastic grain reduction in TMax films using Xtol, as compared to other developers. one additional note, is that 35mm TMax films seem to be radically different from their 120 and 4x5 brethren. I am sure this is not the case, but any predictability with TMY in 120 disappears when I attempt working with 135.

    There is something to be said about what is tried and true! HC-110, ID-11, D76, Diafine (as well as others) have stood the test of time and new emulsions... The old southern saying stands true "..don't fix it unless it's bro ke..." Cheers

    To be accurate, the old southern saying actually goes like this: "If it ain't broke, don't fix it." You can also get away with saying "Don't fix it if it ain't broke." Your quote, "...don't fix it unless it's broke..." has a bit of a northern twinge to it. It just ain't complete Southernese.

    then there's the southernese mechanic's axiomatic response to murphy's law of strange automobile noises...

    me: "Well, it WAS making a sound"

    mechanic: "If it ain't broke, I cain't fix it."

    Bill, I have been using the 5L packages XTOL and never had a problem with it, never encoutered the "ghost negatives" described in many threads. Maybe I was just lucky, or maybe it is the 5L package? I agree, TMAX100 developed in XTOL gives increadibly fine grain - I was almost shocked to see this under the microscope! The grain comes out much finer than what I get with Delta100 in XTOL and approaches that of TechPan developed in Technidol!

    What brownish cast??? I have used XTOL with TMAX, Delta 100 to 3200 films and PanF and never got a brownish cast. Film base is as clear as it gets. I process all film in a Jobo rotary processor, maybe that has something to do with it?

    the film base is clear, though the TMax emulsions takes on a brown/grey colour. quite evident in 4x5. I would have thought it was my Oregon spring water if others hadn't reported identical observations. I see much the same thing with TMax RS and TMax, especially TMY.

    I tried six packages of five liter XTOL and each package gave different results. I used a Jobo and distilled water.

    Bill, I use XTOL for just about everything. I get longer tonality with XTOL over my other developer, Rodinal. My experience is in medium format. I experienced one failure out of 60 developed rolls. Films developed are conventional and not the T-grain type. The failed roll had a slight brown tone. I use 1 litre packages, mix with distrilled water, mix 1:2 for roll film (small tank), toss remainder after 3 or 4 months. There is some question about high Ph reducing XTOL developer activity. Additionaly, Kodak removed the 1:2 and 1:3 dilution charts, a conservative move from my perspective.
