It was one I no longer have a copy of in which you outlines HIE
specifics in list form.  That's why I questioned it when you
originally posted it:  You showed D-76 1:1 as needing 10 minutes at
70F or 11 minutes at 68F--I forget which.  Those are the times for
full-strength D-76 as recommended by Kodak and appearing in the old
PhotoLab Index T&T chart that I've been using for as many years as
I've been using my Nikor developing tanks.

Except in the summer, I normally prefer to work at ambient
temperature--which turned out to be 63F when I processed some HIE last
night.  Using full-strength D-76 and the chart, that worked out to 15
minutes developing time, which yielded good negatives--a bit on the
dense side if anything, I think, but good.  I would like to try 1:1,
hoping for greater delicacy of detail.  Have you any suggestion for
developing time?
