Thanks all for the responses. I heard/read? that using the sodium metoborate predev wash addressed the issue of rapid oxidaton and that this step made using a rotary processor possible. I could be wrong.
But, I also am using alot of developer, 250ml for only 2 sheets. Also, I found this link of Ed's: http://unblinkingeye.com/Articles/Ti...200_grain.html
And I guess my neg's just slightly less contrasty than that one, but nearly the same density. Maybe Im just not used to the stain. But I'll go with Franks suggestion of a 10% reduction, so 12 1/2min tomorrow. And Frank, the Unicolor is the only drum I have now that'll do 4x5, so I'm just using what I have (same w the PMK Donald, next time I thought I'd try pyrocat hd.
Thanks again for the help!
