Hmmm... I haven't used Acufine, but I have used Diafine quite a bit. I
find that shadow information suffers considerably when shot at the EI
recommended on the box. Of course, I've only ever processed Neopan 1600
(shot at 2400!) in it. I love the look of the results, but shadow detail
is not one of its strengths...
