    Yep. I really like the film and am having a good time with the testing. I'm using my office hours at school for it. Got a nice north lit wall to use for a gray card. Did a minus one (6 minute) time today, rocky results, probably because a got a phone call while processing, but possibly good enough; I doubt we're going to do a lot of compression with this fluid anyway.

    Do keep us posted on your results. I'll do the same.

    Will do.

    Lowe was clear about the purpose of the developer,
    to be used in Chicago conditions !

    I'm content to draw a 'barely normal' scale from a linear film.
    I LOVE the look of the stuff, and because I TRY to use a single emulsion as often as I can
    (TMY) E-12 is giving me a touch of that TXP palette.

    Of course, +2 is what the stuff WANTS to do. With APX 100, it adds a LOT of vitality. (handy to have a flashing station in the darkroom, yessir, it is !)
    No grain, though !

    I just thought it would be fun
    Too bad they don't sell stuff in such classy bottles anymore




    Also
    I found some Edwal 20 to try out. It has it's own liquid replenisher.

    Just reading through stuff on the net and happened upon a catalog for Wards 1938 mentioning the new developer Defender 777 "..took 7 years of development to come up with it" so maybe the recipe isn't as easy as 7 of this 7 of that and 7 of the other

    Edwal 20
    Edwal advised using normal EI for 35mm, and half the normal EI for 120 & sheets; the negatives will look thin to the eye but there may be a yellow-brown stain (like Pyro) that will add printing density. PM me and remind me to post the Edwal data if you need it.

    According to a post by Gerald Koch (September, 2003):

    "Gradol is the hemisulfate of p-aminophenol C6H7NO.1/2H2SO4 and has a molecular weight of 158.14. You can substitute p-aminophenol hydrochloride for the Gradol, use 0.9X of the amount called for. No need to make any other adjustments. Do not add sulfuric acid or any other sulfate to the developer."

    Here's from Photographer's Formulary:

    "p-Aminophenol Hydrochloride - 100 grams
    May require a Hazard charge.
    Unable to ship internationally or to Canada.

    Model Number:
    10-0060-2

    Unit Price:

    Does p-aminophenol leave a stain? I dont recall seeing a stain when I used Rodinal. When I get home I will look for negatives from the 60s that were developed in E20 to see if I can a stain. From what I recall the negatives are on the thin side but print well.

    I was summarizing the Edwal literature when I mentioned stain,
    and I flipped back to the formula, saw what was in it and scratched my head.

    The great thing about being clueless
    is that I'm easily entertained. Can't wait to hear what Sun finds.

    I wonder if it might be the ...sulfate. You know, sepia toner is sodium sulfate.

    I'm looking forward to the results also.
