What are now know as old technology films (Tri-X, Plus-X, HP-5, most Euro films except the Agfa APX product)all respond well to D-76/ID- 11, I've always been a sucker for the look of Tri-X in D-76 but I don't use it straight out of the bottle. I use it 1:1 and one shot. I feel that straight D-76 has a little bit too much solvent action on the edges of the silver grains (for the same reason I NEVER use Microdol-X/D-23/Perceptol). D-76 1:1 is consistent, rather non- critical for agitation, perhaps a little compensating for contrast and creates a very pleasing negative to print. I mix my D-76 per instructions then divide the stock solution into smaller glass bottles that I fill to the very top. This greatly extens the shelf- life of the stock solution.(posted 8584 days ago)When I was doing custom darkroom work, I used HC-110 which I mixed straight to Dilution B from the concentrate, I used it one shot in a drum processor and it was very econonical at the volume of film processing I was doing and had developing times for nearly every film on the planet--handy when you are processing film for others.
