    Push or pull?

    Well, sorry if this question has been asked gazillion times before, but i am very lazy to search, so i will ask here.

    Which is you think better to go with, pushing a slow or medium film to high speed iso or pulling so high speed to lower/medium speed? For example pushing 400ASA to 1000 or pulling 3200 down to 1000 [200 to 800 or 800 to 100]

    I personally love the look of Tri-X or HP-5+ (ISO 400) pushed to EI 1000-1600, especially with Acufine developer. If I need very fast film this is what I usually do since the 3200-speed films are more expensive (and anyway my favorite, Fuji Neopan 1600, is no longer available).

    Sometimes I rate 400-speed films at 200 and develop normally (no pull), especially when using the view camera (it's not something I arrived at scientifically, it's just insurance against miscalculating the bellows factor). But if I want a slower speed film, I just get something off the shelf like FP-4+ (ISO 125).

    Depends on what kind of shadow details you want. Pushing Tx or HP5 gives that old school look, pulling (not really pulling as Tmax 3200 can be rated from 400 to 1600,3200 is considered a push) Tmax 3200 to 800 will provide much better shadow detail. If you push meter for the highlights and let the shadows fall where they may. I like Tmax 3200 rated at 1600 and developed in DDX. I also shoot Forma 400 at 800 and push in HC 110 or Studional (sp?).

    I see, each to his own!!!

    Well, i hope to read where i can follow push/pull film so i don't screw up things, and not sure yet to what i want to push or pull the film, until now most of my shots are between 50-400, sometimes closer to 800, but i want to see how can i push a film say Tri-X400 to 800 or even TMAX400 to 800, Also would like to know how to shoot Delta 3200 for 1000-1600 speed, i avoid to shoot indoor with low light because i don't want to go above 800 or 1000, with color it is so easy, i did shoot Portra 800 and got nice results, i don't process color films at all.

    Pushing increases contrast while pulling decreases contrast of the negative...so it depends upon what you need to accomplish, and how you also plan to print (selection of contrast grade).
    Sometimes you push because you need to increase film sensitivity due to low light. I have had to do that, but I never found a need to pull process for contrast control.

    In low contrast lighting - exposing ISO 100 film at 200 isn't going to lose any shadow details - ISO 100 @ 200 best choice.

    In high contrast lighting - exposing ISO 400 film at 200 will gain you shadow detail that you would have lost shooting at 400. ISO 400 @ 200 best choice.

    I normal lighting - You could lose some shadow detail with ISO 100 film used at 200. ISO 400 film used at 200 is your best choice here.

    It ALL depends on the lighting how you expose and process you film.

    Again, it depends on what look you want. Pushing usually doen't really increase the ASA of the film, but just compensates under exposed midtones and highlights. Usually you lose shadow detail too. If you want a grainy look with black empty shadows, pushing can give you that look.

    If you pull, you'll get better shadow detail, but you can pull too far and your negs might give grayish prints.

    These aren't necessarily bad things, but you can use it in your repertoire of looks. It's a creative tool.

    FWIW Delta 3200 rated at 800 looks really neat in Rodinal 1+25.

    The best way to understand what a given film-developer combination will give you at a given EI is to test it yourself and print the results, if a darkroom is available to you. You will find development times for different EIs in most developer/film datasheets. I could describe you my favourite film and developer in glowing terms, yet you might easily find it's not your cup of tea.

    Delta 3200 is an ISO 1000 film so EI 800 is not much of a pull.

    I have only used Delta 3200 once and that was also at EI 800 (developed in Microphen though) and I also liked the results.

    Well, it is all dependable on the look i want so i have to do some tests to come out with the results.

    In fact, the only films i was looking to do push and pull with are specific even i can do with all films, in fact i just shoot the film at box speed after giving my light meter and dig.... camera some readings and do shots, i did print once one frame from a roll i liked, no push or pull, the print came out amazing and the details were incredible [TMAX400], so in most cases if i feel myself i have to compensate the exposure on film i will learn when i should push and pull due to the lighting is there, mostly on those low light or so high contrast lighting i really don't care about the look, all what i look for is to get the shot, better have shots with some details than damaging details in shadows and highlights, God gifted us with film latitude.

    So what are good developers are most popular for those push/pull process? For now i only know about the Diafine, i heard HC-110 from you, what else?
