    Has anyone pushed kodak p3200? I want to push it two stops to try something, i just want to make sure it will work fine and not get too contrasty. i'll probably be using d-76 or something similar to rodinal. thanks!

    I haven't. Want me to move this thread someplace else, maybe to the Q&A or to the darkroom forum? You might get more views that way. Just holler. :)

    actually yes, that would be great! I'm not sure which one though. you can decide :D

    I think i might have accidentally posted it in here and meant to have posted it in the darkroom forum...but it doesnt matter.

    I'll move it to the darkroom and we'll see what kind of nibbles you get. Can always move it again. It can be the traveling thread. :lol:

    Most B&W films can be pushed.
    The downside is increased grain size, loss of shadow contrast and an increase in highlight contrast. You also tend to get an increase in base level fog.
    If you are processing in D-76 then the rule of thumb is an increase in exposure time of 20% per stop.
    If the normal processing time is 'x' then:
    1 stop = x + 20% = x1
    2 stop = x1 + 20%
    The normal limits for pushing is 2 stops. Going beyond that the results tend to be very poor and generally unacceptable.
    Tmax 3200 (according to Kodak) can be pushed 3 stops. But you need to use Tmax RS developer.
    3 stops will give you ISO 25,000!!
    As with all experiments with pushing, it is wisest to shoot a test roll first as all processing times are only guesstimates and you need to check that it works and make adjustments.

    Read the Tmax 3200p tech pub (at kodak.com), and you'll find out that Tmax 3200 is really Tmax 800. My experiences with Tmax 3200 shot at 1600 and 3200 is that it is pretty contrasty, and the grain is very coarse. I've had finer grain results pushing Tri-X 400 and Tmax 400 to 1600 or 3200. I'll admit that I've only shot about 2 dozen rolls of the Tmax 3200 though, and hundreds of rolls of Tri-X, so I've definately put more effort into figuring out pushed Tri-X.

    well i'm trying a few things to get alot of grain (hot water for stop bath is one i might try), and i might push 3200 two stops for fun, just to see.

    I pushed tmax 3200 just one stop only last week! (although I'm not like you hard core darkies... I got it developed at a lab)

    It turned out nice and grainy but it did become very contrasty with just being pushed one stop... so be careful with the 2 stops!

    I've actually had better results pushing Ilford 3200 one stop. The contrast wasn't as extreme although it was increased... and there was lots of nice big grain. And the highlights still had good detail in them.

    Unfortunately last time I pushed Ilford 3200 the lab forgot to push it... and developed it at 3200. Bastards. :-(

    yep delta 3200.

    I'd scan you in some of my pics but my scanner isn't scanning properly at the moment. It's stuck on black and white and wont scan in grey scale. GRRR!

    Reticulation, if I recall right this cause large black dot and also can cause cracking. Only tried it myself a few time, first back in the 80’s with plus-x it worked OK, then I tried it last year with the last plus-x it but send to have no effect (most new films are engineered to reduce conmen errors), I have been think about try it again but this time with Adox/Efke film it has an old style emulsions
