    FWIW, the lowest price I've found on ascorbic acid is The Chemistry Store, perhaps because they sell "technical" grade, which is presumably unfit for human consumption but works fine as a developing agent. It's best to order from them if you want other chemical supplies, though, to avoid paying too much on shipping, on a per-pound basis.

    IIRC (Edit: and I didn't recall correctly), Trader Joe's price on the food grade sodium ascorbate is roughly the same as The Chemistry Store's tech grade ascorbic acid, so if you have one nearby, it's probably the most economical. You also don't need to do the baking soda conversion that titrisol mentions with sodium ascorbate. The Chemistry Store doesn't list sodium ascorbate, and Trader Joes' doesn't sell online.

    Edit:
    Please note that Trader Joe's carries ascorbic acid, not sodium ascorbate, as mentioned in several following posts. My four month old recall failed me. At least I had the price right. I apologize for any confusion or wasted trips to Trader Joe's.

    Are you sure that Trader Joe's sells Sodium Ascorbate? I've only seen Ascorbic Acid powder at TJ's, for $ 9.99 per pound.

    I've gotten some very interesting results using PMK. That said, I'm now in the process of trying out PyroCat because I want to see how the printing characteristics differ on VC paper between the two developers. Specifically, how brown colored stain affects contrast vs yellow green colored stain.

    I switch back and forth between Xtol 1:2 and DD-X 1:4 depending on whether I have the time to mix up the Xtol or not. I don't see much difference between the two. But then again I'm not one to haul out a densitometer either. The proof is in the prints and they look fine to me. I was EXTREMELY upset with Agfa disco'd APX100 in 4x5.

    Ditto for me. I use Trader Joe's Ascorbic Acid powder in various developers - works great. I have never seen Sodium Ascorbate in Trader Joe's (Thousand Oaks & Manhattan Beach, CA).

    I find Paterson FX-39 gives finer grain than Rodinal 1:25.

    Sorry folks. My mistake. I was going from 4 or 5 month old memory and didn't have time to make the 25 mile round trip to check the product itself (and you can't check online, which I did try to do before posting). I already had NOW foods sodium ascorbate and another brand of ascorbic acid by the time a local Trader Joe's opened here early this last spring, so only saw the product on the shelf and didn't need to buy any.

    I apologize for any confusion I caused, and will edit my original post to correct it.
