A recent post on APUG by Ron (PE) the photo engineer who said that one of the
last research topics by Kodak before they closed their R&D group was in long
development times for best image quality.

Subject: [pure-silver] Does Shorter Dev Time Always Give You Lowest Grain?
For N Development of TXP 120 @68F, I do the following:
PMK 13 min / 15 sec agitation
HC-110B 4.5 min / 30 sec agitation
D-76 6 min / 30 sec agitation
Is it the case that the shortest development time will always lead to
the least grain or does the formulation of these different developers
contribute in ways that makes this rule of thumb incorrect?
To my eye the HC-110B does seem to yield the lowest grain but I haven't
done carefully controlled tests with the same batch of film and subject/
lighting conditions.
