    After buying a 4x5 camera, lens, tripod, tripod head, film holders, film, developing trays, developer, and fixer, I think I'm finally ready to expose and develop my first LF negative. I loaded eight sheets of HP5+ into film holders this morning and I'm ready to expose.

    What I'd like to know is there someone who can give me recommendation for a HP5+ film exposure index, Pyrocat-HD dilution, tray development time, and agitation (e.g., continuous shuffle agitation) combination that works for them. Oh, and before someone says read Sandy King's unblinkingeye.com website, I have and have not seen a directly applicable combination for hand processing in trays processing.

    Thanks,

    Using 8x10 HP5+ my numbers are:

    2:2:100 (I develop 4-6 sheets at a time in ca 3 liters of solution)
    74F (typically declines to 73F by end of session)
    2 min presoak in water
    constant shuffling
    water stop

    HP5 rated at 250ASA
    N developing time is 9.0min
    N+1 developing time is 10.5min

    hope this helps, good luck
