While we're on Mortenson, why did he develop cold? Is there some
advantage to doing stand development in the refrigerator? Does
it delay the onset of fog? Is it possibly something only
applicable to the very different films of his era?  I've found I
actually prefer stand hot with films that can take it. I do my
TMY pushes as 20-25 minutes stand in 1:1 Xtol at 90-95F, works
great, a little fog but zero speed loss. Delta 3200, however,
seems to lose speed into the fog at anything over 68F, even at
15 minutes.
