    You can develop two o more different isos at a time?

    I'm planning to develop two or three different isos in the same tank with the same developer to and with the same time. Would it be possible?

    I use Paterson tanks for 120 (or 35) I have a few and can use2.3,4 or 5 reels I prefer a maximum of 3. For LF I have Jobo tanks (pre rotary and two spirals that hold 6 sheets each. You use the volume of developer to cover the spirals and agitate by inversion I use 3 inversions every minute.

    I only process certain films together where I'm happy to use the same development times.

    Yes that's what I meant, I process Delta 100 & HP5 orAdox/EFKE 25 at the same time or Fomapan 100 & 200 together but I don't mix the Foma films with any others as they need a much shorter development time.

    It is possible if all the films require the same developing time.

    It would be possible but you need to know your films and personal EI (exposure index) for each of them and really that comes with experience, it also depends on the choice of developer.

    I thought so ... I think it is possible to use a very dilute developer such as rodinal 1 +100 and develop for an hour without stirring. I was also thinking about developing with a divided developer and finally a homemade developer for color with cd4, cd3 or cd2, What do you think?
    Thanks
