    As I have said before, that blix is in my EK notebook as Blix 1066 denoting the month and year that it was first formulated. I transmitted that formula to Kodak Park at that time. It has changed little since then. I wish I had one penny for every gallon of concentrate that Kodak sold. If so, I could afford to make house calls to teach RA4 processing!

    Maybe you've commented on this elsewhere PE, but what is your thinking on 2 bath vs 4 bath?

    I'm not sure I know what you mean Wayne.

    Develop, Blix, wash! 2 bath. Develop, Stop, Blix, wash, 4 bath. (including washes.

    Then there is Develop, Stop, wash, Blix, wash and the possible Develop, Blix, wash, Stab which is used in any of the other combinations as well.

    I don't recommend a Bleach then Fix with paper. I do recommend it with film.

    Try them all Wayne, and just use what seems to work best for you.

    While the blix may not smell too bad, you can become quite sensitised to the possum piss* and end up with breathing difficulties and/or contact dermatitis. Reducing exposure via use of drums is (IMHO) the best option.


    * excellent description. It's full of amines of some sort.

    I use a Jobo for my RA4 (For some reason my Durst Printo is giving me staining). What times do you use for doing room temp? I use Kodak RT kits.

    That's what I was wondering. I haven't looked at all the options out there but I presume one of them has separate bleach and fix steps.

    You forgot one:
    Fix, Stop, Develop, Swear.
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    Yeah, I was wondering if we could get a time/temperature chart or list that goes to lower temperatures (like down to 68 that PE mentions) than the Kodak publication.

    With RA-RT developer replenisher and no starter, I use 2' at 68 and 1' at 100. Draw a line through these. I use tray at 68 and drum at 100. For large prints at 68, I use a drum sometimes.

    My color varies by no more than 10M or R depending on the phase of the moon.
