Bob,
Well of course its entirely subjective. I like what I think is enhanced
sharpness/edge effect that I get with the DK-60 1:3 over other developers. The
DK-60 I use is from a can(I have about 15 cans) that is likely to be 20 years
old or better. I'm sure it is the same as in the Photo Index, the canned
developer I'm using is Kodak's. 1:3 dilution allows me to used times that are
in the 8 1/2 to 10 minute range. I've used it for 32 Panatomic-X, 100 T-Max,
100 Delta, Acros, 100 APX, Plus-X, FP-4, 400 T-Max, Tri-X, HP-5, 400 Delta, 400
Neopan, and others. I believe the can will make about 12 or 13 liters. (I'm
responding while on a break at work so the details are from memory and I have
CRS). Using it 1:3 makes 13 liters last for a long time.
In the past I've used Xtol, lots of scratch mixed developers with hydroquinone
and phenidone or metol or even sodium ascorbate such as D23 or D25 or Gainer's
mixes, PMK, HC-110, etc. If I should ever use up all the cans of DK-60 I have,
I'll mix it from scratch using the Photo Index formula. I'll likely keep and
use the PMK on occasion till it is gone or bad, but I'll give away the other
packaged developers I have on hand because I feel like the DK-60 is best.
I'll get you some times when I get home tonight. I've been using Panatomic-X
and 100 T-Max lately, and the times at 68 degrees F have been 8 1/2 for the
Panatomic and 10 for the 100 T-Max. I use a Patterson tank, agitate by
inversions for the first 30 seconds, and then 4 inversions every 30 seconds
after that. I use 68 degrees F as the standard temperature and adjust the time
according to the standard time/temperature chart and the temperature of my
mixed developer. The developer gives me negative which prints properly on a
variable contrast paper(usually PWT) without any contrast filtration.
And once again, its all subjective on my part, I've not done any test other
than looking a the negatives with a 15X loupe, and printing them.
