    How many 35mm rolls per liter of 1:50 PC-TEA is appropriate (at one developiing session)?

    Using 100ml TEA, 9g C, 0.25g P concentrate.

    thanks, Robert

    Given I can safely do one 36 exposure film in 400ml (8ml PC-TEA), I'm guessing at least 2.5 :wink: I've also done two rolls in ~ 600ml (12ml PC-TEA)

    Based on the above, I think you should be able to do three rolls at a time in one litre.

    I routinely do two rolls at a time in a half-litre tank, so I'll up the estimate to four. :smile: But I assume the OP is asking about reusing the developer for more than that, which I've never done---it's so cheap that it never occurred to me *not* to use it as a one-shot.

    Note that Kodak recommends using diluted Xtol only as a one-shot (the concentrations of developing agents in PC-TEA 1+50 are somewhere between Xtol 1+1 and 1+2, IIRC).

    I'll put that in my "database". In the meantime, early this AM I did 7 rolls in using 1500ml 1:50 and last roll (done in pairs), showed a bit of a change. My first experiencces with PC-TEA are really good, I'll be working with this.

    Thanks, Robert
