DD-X? :)
DD-X
Dilute it at 1:9 and increase your 1:4 time in 60% for a start, see if you like, need more?Increase further.
Regarding sharpness, well, accutance might be a better term, but yes it's a fact, higher the dilution, higher the accutance.
So, the previous friend stated he got more grain at 1:4 dilution than 1:9, well, I don't shoot that much 35mm nowadays, but if my memory isn't failing, wasn 't precisely the contrary? Higher dilution, more grain
I have used DDX at 1:9 AND 1:11( for the newer TMX emulsion ) for a long while now. I ran film tests utilizing TMX ( as noted, new and old emulsions ), TMY, HP5, and Delta 100 using the BTZS sytem, my Jobo expert tanks for 4x5 film and 8x10 film, 75F ( in Florida ). I ran tests for conventional silver printing and contact printing, and for doing contact prints for Pt. and Azo. Yes, the tests were involved, but worth it. I can tell you without personal reservations that using DDX at 1:9 produces very sharp negatives that print without any problems at all using Grade Two filters ( or equivalent ) on VC paper, and on graded paper. Indeed, except for the expected higher contrast of negatives developed in Pyro, I see little if any difference with reference to accutance in the negatives developed in DDX vs. those developed in Rollo Pyro using conventional contact prints of 8x10 negatives ( get ready to duck!! ). I believe that such large contact prints are a very good "eye-ball test" to use for the comparison of DDX with RolloPyro as far as negative and print quality are concerned. Caveat: I have not yet done contact printing with the Pyro negatives using Azo/amidol or PT. so as to be able to compare DDx developed negatives with Pyro developed negatives using those "alternate process" techniques.

Ilfotec DD-X works great at 1+9 (i.e., 1:10 dilution). At this dilution, it makes DD-X a contender with other developers that otherwise cost less.
Not only that, but it also gives nice tonality and relatively fine grain. I like DD-X 1+9 almost as much as HC-110 Dilution B.
