    I use PC-TEA as well as Mytol - The PC-TEA is very good but Mytol has the edge in fine grain --- probably because of the small quantity of sodium sulfite - even 1:1, Mytol is finer than PC-TEA - If you are enlarging big - you will notice. I tend to use PC-TEA with FP4, APX100 or HP5. For Tri-X, I always go with MYTOL.
    My photos are always without all that distracting color ...

It falls outside the realm of standard Metal/ HQ or Staining developers as the primary ingredient is a cousin of Vitamin C. Which is friendly to yourself and to your sewage system. You can make your own:
    MYTOL
    Distilled Water 750 ml
    Sodium Sulfite 60 g
    Sodium Metaborate 4 g
    Sodium Ascorbate 13 g (purchased as vitamin C)
    Phenidone 0.15 g
    Sodium Metabisulfite 3 g (same as sodium bisulfite)
    Distilled water to make 1000 ml
    If you don't want to mix your own, use Xtol. If you want to mix your own, a very simple (3 common ingredients) is easy. The above MYTOL will work fine, except that the sulfite is totally unnecessary and does nothing in a Phenidone/Ascorbate developer.

    Consider trying this:

    water 1 liter
    5 g (1 tsp.) sodium metaborate OR (depending on your desired developing time and level of activity) 6g (1 tsp.) sodium carbonate
    4 g (1/2 tsp.) Vitamin C crystals or powder from your health food store
    4 ml. 1% Phenidone stock solution (I dissolve 1 g Phenidone in 100 ml. 90% isopropyl alchohol from the pharmacy.)

    Try a starting time around 6-7 minutes at 72F (22C). You may have to play with it a bit to get the time you want, but that will get you in the ballpark.

    Use this as a one-shot. Takes no more than 2 minutes mixing time. Very fine grain, full tonal scale. I call it PCM for the phenidone, Vitamin C, metaborate version or PCC for the carbonate version. I find the carbonate works best with Delta 100, Fuji ACROS, while the metaborate version works best with Delta 400. For the slower films, the metaborate version needs 9-10 minutes.

    Larry,

    Is that sodium ascorbate as in the Mytol formula you quoted from Frank Hovie, or ascorbic acid?

    Thanks,
    Lee

    Perceptol is no longer

    D-76 is a solvent developer, When used full strength, because of the sulfite containt. It desolve the grain a tiny bit making them apear finer. There is true fine grain developers like Perceptol.
    Cheers Søren
    Hi Perceptol has been discontinued 12/04 I recommand ID-11 for the best grain now Perceptol was so fine grained I didn't have grain!!! On Ilford 50 asa pulled to 25 ASA develped 1:3. I am starting over with ID-11 again 1:3 I'm a have huge fan of extended development times. Ilford rep told me that the Perceptol was over kill on grain in 1:3 and I would like the increased sharpness (if that is possible I felt I was so sharpe already) and my grain still would be very fine. Time will tell has I have just started again in B & W after long layoff. Mario > Giordano

    The fellow who compounded MYTOL, the homebrew XTOL; he did
    not know that the sulfite in his formula was "totally unnecessary"
    and "does nothing"? Imagine that. Dan

    Sodium Metaborate is the same as Kodak's Kodalk and its new name Balanced Alkali.

    Borax is Sodium Tetraborate, more commonly known by its trade name, 20 Mule Team, available in grocery stores.

    If the Sod. Sulfite does nothing, then what acts as the preservative for the developer? Does the Vit. C do double duty, preservative AND developer?
