    Does anyone know, or have a time for developing agfa 400 on 800 iso, in developer D76 or HC110 (1+31) or michrophen?
    thank U

    Wow! I looked everywhere, since I really like the AGFA APX's (both 100 and 400 and the long lamented 25...). I have to say though... I like them, but they are quite full of character (read: grain) for their given speed, and 400 even more so - I don't know if I would choose this film for pushing... Actually, I don't and that is probably why I have not realized after several rolls of it in both 120 and 35mm in the last couple of weeks, that I DO NOT have that info ANYWHERE!!! I thinkn most people echo my feelings, because it seems that apx400 is best left alonor even pulled a bit. I looked everywhere - the closest I got is here, and here , but still no definitive answer...

    I'll join in on this - I would really like to know if anyone has done it enought to be able to provide a grain-taming (and I like grain, so it must be pretty wild!), tried-and-true push process for this film.

    If you can obtain Acufine developer (or its twin Ethol UFG), I think you will find it capable of developing a very usable image on APX400 that has been exposed at a speed of 800. Sorry I have no information on the other developers you asked about. I can look up time and temperature information for APX400 in Acufine later today if you have any interest in this direction.

    I get my best results from APX400 when exposed at about 250 or 320 and developed in PyrocatHD or, recently, a home-made Ascorbic/Phenidone/Carbonate developer. But I have found that APX400 and Acufine work well enough together for speeds of about 640 in overcast and 1000 in sun. I use 120 film and enlarge to 8x10, so the much-ballyhooed grainy character of APX400 causes me no problems, even in Acufine.

    For what it's worth, this weekend I've developed APX100 (not 400) at EI 200 by using the same devel time and warming the developer to 25C. The contrast will increase, but it's a quick and easy method to gain a stop. I'll proof the negative tonight so I can give you some rough details if you want.

    Here is my APX400 developing data (120 format, printing with condensor enlarger on Agfa MCC and MCP):

    Acufine 1:0, standard agitation: 7.5m at 70 degrees F

    This is good for EI640 in diffuse light and ~EI1000 in direct sunlight (the attached photos werre made with the APX400/Acufine combination).

    For Pyrocat HD 1:1:100, I expose at EI250 and develop for 11m at 70 degrees F with standard agitation.

    I am baffled - I didn't expect this to be such an enigma... APX400 is a pretty common, fairly popular film... are people scared of the grain? Because it really is not that bad - I figured someone would have needed to shoot it at 800...

    last night i made a test, and develope a part of agfa in D 76 on 20C 11.30 min. for now negativ is ok, for a weekend i'll make some test on the paper to see the contrast and grain.

    Since grain is a problem with the new APX400 I'd give it a shot in Microphen.
    DDX 1+4 for 16 minutes gave me good results, and IIRC that is almost equivalent to Mirophen 1+1
    So Microphen 1+1 for 16 minutes should be in the ballpark

    last night I mad ea few copies from this experiment, and tehe results are good, grain is good like on 400 iso in d76, so I fix the problem
    very soon I will make i big copies, so that we will see the grain and contrast

    I know my response will not help in the situation present. Also, I realize that it is bad form to answer a question with a question. Still, if asa 800 is required why not use Delta or Kodak 3200 which has an honest rating of 800?

    A friend of mine works at a professional lab doing nothing but developing film. They use Xtol at full strength. He tells me their dip&dunk system has a seasoned tank, which depleats the strength of the Xtol a little bit, due to residue from film, and other factors. They basically keep replenishing it.

    In the case of APX400 at EI800, they normally run at 7min10s. He estimated about 6 to 6-1/2 minute with freshly mixed Xtol at full strength, developed in normal daylight tank with normal agitation patterns.

    Hope that helps,

    - Thomas

    You can try the times listed here for Rodinal. It's in Finnish, but the times are easy enough to read :smile:

    Ah, so I am not going nuts - the new APX400 is a bit of a beast compared to the old! I thought maybe I was just seeing old prints through rose cooured glasses!

    apx 400 @ 800

    If you've got one chance to do it, try D-76 1+1, 18 minutes @ 68. Agitate once a minute.

    If you've got a second roll, PPPLEASE shoot it at 800, and cut a strip off and try the development.

    good luck
