    I posted a question a few days ago about this developer but didnt really get any answer. Maybe it is because I used the wrong subject line :sad:

    Here is the orginal post;
    http://www.apug.org/forums/showthread.php?t=8015

    I am wondering if this is a good developer. I have been wanting to use XTOL but want to roll my own and I have read that MyTol is it equivalent.

    Can anyone that used it give any feedback? I like the look that XTOL gives but want to start mixing my own chemistry. It looks pretty easy to mix (MyTol) but really need to get some feedback for experienced users of it.

    Thanks,

    Kev

    Try DS-10. I use it exclusively for Delta 100, Delta 400 and 400TX. Excellent sharpness and grain, easy mixed. You can replace the (not easy obtained) Dimezone-S with Phenidone, you shouldn't mix it very long before usage, though. For extreme sharpness try DS-12 with APX100.

    Kevin, I haven't used Mytol but I have used Pat Gainer's PC-TEA. PC-TEA produces results that are fully comparable to Xtol and has the advantage of a very long shelf life.

    FYI, Xtol, Mytol and PC-TEA are all Phenidone - Ascorbic Acid (or Ascorbate) developers. They all produce excellent and similar results. The PC-TEA Stock Solution does not contain sulfite or water. Xtol and Mytol stock solutions do contain sulfite and water.

    Expected shelf life for the stock solutions.

    Xtol: About 6 months, for Stock Solution stored in glass bottles.
    Mytol: About 6 months, for Stock Solution stored in glass bottles.
    See: http://www.udmercy.edu/crna/agm/phenvitc.htm

    PC-TEA: Expected to have longest shelf life - by far. My PC-TEA stock solution has now passed 4 months with no activity change seen in 1 liter of stock solution stored in a Nalgene bottle.

    Re DS-10 with phenidone shelf life, I've emailed Ryuji on the subject, but never had a reply.
    I feel he's quite pessimistic about it. See the link posted by Tom and there's Microphen...

    I mixed Mytol several times thru the years, finding that stored in a closed full glass bottle to be no problem, but once opened live seems to be pretty short. I use a film leader in a 135 film container and add Mytol 1:1 and check for dmax after 10 mins. If the leader looks too thin, I rather mix a new batch. Last time I used it I collected enough films to use up 1 l as 1:1 mixture, which is 8 films in a Jobo 1520 one-shot.
    I really like it with Delta 400 and 3200 (@1600)
