    So I picked up some Ilford XP2 Super in 120 for my Mamiya and I was reading about pushing/pulling the film. Here is an interesting bit of info I found, is it true that you do not need to change development times if the camera is set to speeds between 25 and 800? Meaning you can push and pull on the same roll? I tried searching but couldn't find anything to back this up.

    I do -1 to +3 stops regularly and never tell the lab to push it. Simply works. XP2 has a big latitude it seems.

    Yup, it works....and of course C41 Colour process.

    Most color negative film has a similar latitude and XP2 is simply a one color, color negative film. Actually most 400 speed B&W negative film has a similar latitude for normal scenes.

    This doesn't mean mean there's no point in metering, just that you have options if you need them.

    And Yep, it's a great film for any situation where the ability to meter or set exposure is limited, like with toy cameras, without the need for development changes. This is how disposable cameras work too.

    Thanks for the info guys, I think I'm going to have a lot of fun shooting this film. I think I will start off shooting it at 100 and then work my way up through to 800 and see the effect pushing and pulling has on grain structure :smile:

    For those who already have experience, what did you guys find?

    Thanks again!

    Just FYI, pushing & pulling are development changes.

    What you will be doing is simply changing exposure placement.

    LOVE the stuff for studio portraits with strobes or hot lights. Usually rate it ISO 100/160 in 120. With 35mm, available light, fast lenses and a monopod, ISO 800 is no problem.

    Back shooting it again now and prefer it to Kodak's C-41 B&W materials. XP2 seems to be made for hybrid work.

    I used to use this film, but that was nearly 10 years ago. I played with the exposure times myself and from what I experienced, the results were nearly indistinguishable between 100 and 400 ISO and only sligtly worse at 50 and 800 ISO. ISO 50 was a bit more contrasty and ISO 800 a tad more grainy and duller, but only slightly.

    Ilford had a major problem with labs not liking XP1, it was a superb film but needed non a non normal standard process time in C41 developer something which few labs catered for. Ilford published times for their own XP1 developer ansd C41 which included push p[rocess times for speeds abovec 800 EI.

    The film was reformulated as XP2 (later Super) and is designed to be processed at the standard C41 time. Ilford dropped the push processing recommendations because few labs would do it but in practice it's still an option and I continued to push process my XP-2 to 1600 & 3200 EI in C41 chemistry until about 2001/2. I remember discussing this with a senior Ilford chemist, and to sales managers, in the early to mid 80's and they confirmed taht while it was obviously still feasible the recommendations had been dropped because Ilford wanted a film with 100% processing compatibility with C41 minilabe etc.

    For my use push processed XP1/2 gave far better results than HP5 etc.

    Thanks for pointing that out, indeed the development times will be the same so it technically isn't pushing or pulling. When I made the post originally I thought I might have to change the developer times :smile:.

    I've developed this film in B&W chemicals as an experiment, and it came out great. The masking clears nicely, and you end up with traditional negatives. Scanning hasn't been a problem, either. The latitiude is slightly rediced, it seems, but still nice.

    Kodak's C-41 developed in traditional chemicals doesn't clear and comes out terrible!

    I have some pretty high hopes for this film :smile: I'll be using it with a Hoya yellow filter and processing it at home with my Unicolor kit. Like I said I plan on shooting two frames at EI 50, two frames at 100, two frames at 200, etc all the way to 800 (keep in mind this is on an RZ67 so I get 10 shots per roll).

    I haven't tried it, but it certainly should work. As stated, XP2 is essentially a one color color film. Color balance, which can be affected by pushing a color film, doesn't really matter here.
