Any D-23 users?

FP4 at EI 50 looks superb in Perceptol and since D23 should be close to it in composition I wonder if there are any users of this Kodak formula containing only two ingredients. I'm temptet to make it myself.

D-23 types are often used as part 1 in 2 bath developers. It's OK for single solution, but I much prefer D-76/ID-11.

A Perceptol type formula can be found if you search for Edgar Hyman's fine-grain developer.

Metol 5g
Sodium sulphite, anhydrous 100g
Sodium chloride 30g
Water to make 1 litre.

I like very much D-23 - I use it mainly diluted 1+3 because I normally have a lot of light and contrast, but I've never used it with FP4. In my opinion, generally speaking, if you develop with D-23 you should divide by two the ISO proposed by the film manufacturer.

It's really easy to prepare it at home.

There is an old fadu thread here relating to D23.

Unfortunately the fadu search facility is currently not accepting three character searches

Thanks to all. It should be a good fit for LF film and tray development.
