>I agree, Edward. I have shot approx 12 rolls over the last 10 months with
no reticulation. My experience with retic. is that it appears when the film
has been thermally shocked during processing. That is, using a stop or fix
or wash at a temp. difference greater than  (say) 10 degrees F. I process in
a JOBO that permits temp stabilization for all baths. However, before the
JOBO, I often processed with just a Patterson tank in a water bath that also
held the dev, stop, and fix. K750 is somewhat grainy by nature, something I
find pleasing in the context of IR images. BTW, I look forward every day to
the IR mail. Always something interesting.
