I've never read anything good about D-19. It seems to be simply beyond every other developers for everything. In some way like Rodinal except that there is no aficionados for it.

My friend that gave it to me has some really interesting results with Ilford PanF+. It has a very unique look.

i'd love to see something.. with panF it has to be rather contrasty .. but a nice pull could be interesting.

what are the ingredients/components? Maybe look on photoformulary for something similar and see what they say.

Luke H- I'm intrigued by this developer, I might have to try it with some of that microscope film.....found this, don't know if it will be of any help:

I'll mix up the powder and try a test roll tonight.
I think it'd be a good developer to do dramatic portraiture in the daylight with when you have low contrast scenes.

Years ago in physics and optics courses I had used D-19 to develop Agfa holographic film. The development times seemed rather quick, but we developed cut sheet film in trays under green safelights. The film was equivalant to something like 0.5ASA.

It's fun stuff. I've been playing with it, haven't really "dialed it in" yet.
My first batch was pretty well behaved, but I hadn't mixed it properly - had some sediment left over, and lawd knows what was in the sediment. No idea whether what fell out was proportional to the ingredients in the powder; it might have been whatever makes it dee-nineteenie. So the batch probably wasn't the real deal.
Now that I have it full strength (the tap water hadn't been hot enough, and I had it almost boiling this time), I've had a little trouble getting it under control. Ruined most of the shots on the first couple of rolls. So I cut up part of a roll of APX100 and experimented with times, found that 3 minutes looked pretty good, though that's a bit too fast to deal with if I'm going to have a predictable rinse/stop.
Diluted 1:1, for 7 minutes with one inversion every 30 seconds came out fairly well - some highlights still blown, but what seems to me a nice kick in the dark areas.
I don't know if that indicates a sort of nonlinearity, or it's still a touch overdeveloped, but it'll be my new starting point.
Given the expense of the stuff, there may not be much reason to try D-19 on traditional b/w emulsions unless you run into a bunch of it cheap, as I happened to.
Still waiting to see your test roll, Luke. :)

In digitaltruth's formulas, they say starting point 6 minutes. Knowing that PanF+ is so contrasty to start with, I'd try a short roll at 5 minutes...

D-19 is a contrasty developer for scientific films such as electron microscope and x-ray. I tried it with Tri-X @ 1:2 dilution for 6 minutes. looks ok for the higher contrast effect

5¢: Did you let it cool to proper development temperture before using or did you use it hot?

From Anchell's Darkroom Cookbook: (3rd Ed. Formula #29 p220)
High contrast with good keeping properties and high capacity for continuous tone scientific / technical work and also for some reversal processing.
It is a metol / Hydroquinone dev with a high proportion of Hydroquinone and lots of bromide
He suggests undiluted, 6mins @20'C

Wayne, I use it at 68F. The high temp was just for mixing.
Lately have been trying D19 in weaker dilutions like 1:9. The results are sometimes wonderful, but sometimes I'll screw up a roll from too much contrast, even at that dilution.
It's fun to experiment, but when I have pictures I really care about, I usually fall back on the more predictable xtol or rodinal depending on the film.

Thanks. I love contrast so I'm thinking I'll have fun with the packs I have. Just not sure when I'll be mixing it up.
