Hi Christer,

I used the nominal 25, and the result was fine. Perhaps the continuous agitation of
the Jobo made a difference. I always use a 5-minute prewet with the Jobo, both to
bring the film and reels to processing temperature and to ensure even development.
It may or may not really make a difference, but I do not mind doing it.

The DDX is working fine. So far I have used it with Delta 100, 400 and 3200. It
works well with all 3, but I have not nailed down the exact development time,
dilution and temperature with the 400 and 3200 yet. With the 100, I have settled on
12 minutes at 24C with a 1+9 dilution. Wonderful results. I will be trying this
kind of combination of higher dilution and longer time/higher temperature with my
next roll of 400. I am still aiming to arrive at just one developer, whether DDX or
XTOL.
