    APX100: which developer for the finest grain?

    I suppose the title says it all. I've been developing APX100 135 in Rodinal and I love the results. It is a bit grainy for a 100 speed film, so I was wondering what you guys and gals use for a developer with APX100 to get super fine grain.

    Thanks in advance,
    Ara

    I use DDX for the finest grain.
    However Rodinal 1+100+vitamin C gives similar results with better sharpness

    I've heard about using vitamin C, but never investigated. Obviously, it's not vitamin C in tablets. Where can I buy it, in what form and how much should I use? Also, what exactly does it do for the development process?

    I think Patrick Gainer is the best person to ask about how does that work.

    From his writings/teachings/messages I have done the following:
    - Ascorbic acid or erythorbic acid can be bought in powdered from from a health store, trader joe's or now foods online. Sodium ascorbate would be best but I have iso-ascrobic acid now.
    - I mix 1/2 tsp of ascorbic acid per 300 ml of water, then neutralize the acid by adding baking soda slowly until the fizzing subsides and then add the Rodinal
    - Development times for 1+100+C are the same as 1+50 [without the C]

    Read the article in unblinkingeye about Rodinal, at the end there is a note explaining how this works

    Paragraph 7 in the above article gives you the info from Patrick "Gadget" Gainer via his correspondence with Ed Buffaloe. I've tried it on one roll of HP5+ so far and liked the results. It also gives higher EI ratings than Rodinal alone, as the combination is superadditive.

    The Vitamin C is as sodium ascorbate, available from NOW foods, perhaps at a vitamin or health food store near you, but also online from NOW foods. Trader Joe's also carries the correct form at a good price.

    Google on "gainer C rodinal" and you'll learn more.

    Other fine grain devs include, but not limited to: D-76 1+0, Microdol-X, Perceptol, and the PPD devs which you can mix yourself or buy from Photographers Formulary.

    I just developed a 120 roll (6X9) with a Ewal 12 clone, very tight grain and sharp. I am looking for a replacement for120 Plus X and have 4 more rolls of APX100 and plan to develop them in Microdol X, D76 1:1 and Acufine at 200.
