    Rollei IR400

    I recently bought a roll of Rollei IR400 and a Hoya R72 filter, and right now I'm just trying to sort of figure out what kind of compensation I should take into account for exposure times.

    Also wondering if anyone knows about developing times with D76.

    Thanks.

    For the r72, I'd recommend trying a compensation factor of about 8-9 stops, assuming that you're in good sunny-16 weather and your scene contains fresh spring foliage.

    I think I developed per the massive dev chart last time around and it was fine. So, presoak and then D76 or ID11 at 6 minutes, stock, 20C.

    It's probably a good idea to bracket exposures as well.

    Have a look here and especially here, but you should also consider bracketing. Focus for IR if you have that choice.

    Iso 6 with a Hoya 72R. (RG720nm) But a lot is depending on the amount IR light in the atmosphere.

    Here is the Rollei developing table:

    I have been playing with the same film, and after 2 rolls of 35mm and a couple sheets of 4x5, compensation was closer to 9-10 stops, and my dev time with xtol 1:1 was 14mins

    I'd agree with RobertV...ISO 6 with 89b filter (R72) and bracket.

    Thanks RobertV for your Rollei dev chart. I've been looking for something like this for a few weeks.

    No problem. It's important that you have the right data.
