Good results with HP5+ (also 400TX) and DK-50 1:1

[John Wiegerink]

With T-grain 400 @ box speed I use DK50 1+9 for 14 min at 20C. The results are excellent. I found times to be remarkably like FX55 times for some unknown reason.

I should add that subbing the metol with Phenidone 0.25g will get you FX37

Good luck

Murray,
I have a fresh batch of FX37 mixed now for use with some Kentmere 100 in 120. I haven't tried any of the Kentmere films and thought FX37 would give me honest grain since there's very little solvency. One nice thing with DK-50 is that it's a very simple developer to mix and use. The chemicals are not exotic and easy to get. Plus, I have a bunch of Kodalk (sodium metaborate) on hand. Oh, and some Aussie wine bladders to store them in.

Thank you Michel Hardy-Vallée and Murray!
I totally forgot to check in Film cookbook.
Maybe 40 years ago I made one batch of DK-50 and figured out that is very similar to HC110.
This time I made it from old Kodak package.
I went to 1:5 (to make easier with measuring 300ml for paterson tank) for 10 min.
So far I like what I saw on negatives and first test prints.
Next time I will try Murray's dilution and time just to see is there any difference in highlights.

I wrote up my observations on DK-50 back in 2015:

DK-50, Still alive and well?

After a several year hiatus, back into film and film processing. My interests in B&W chemistry have been mostly around Divided Development and the replacement of hydroquinone with ascorbate alternatives. I decided to go where no Paul has gone before and to play with DK-50 for a number of...
