    One thing I've been wanting to ask. The Dektol first step is at what temp?

    The entire RA cross process can be run at 68 deg F (20 deg C).

    First deve 2'
    stop 30"
    wash 1 - 2'

    reversal exposure and room lights

    Color Dev (RA-RT) 2'
    Stop 30"
    Blix 2' - 4'
    wash 10' - 20'

    I only make RA-4 chemicals up in small amounts so I'd still likely run it in drums. Is the long wash because of the temps or the whole process?

    Wash time is a function of temperature only. Go up in temp and down in time on a scale with 10 - 20 mins at 20 deg C and at the other end 2 - 3 mins at 40 deg C and you have the approximate nomograph with outer limits set and inner limits set.
