For the love of DS-14

[removedacct3]

For the love of DS-14 and to satisfy my own curiosity ... who is regularly using DS-14 and what are you experiences?

I like it a lot as it is easy to mix, replenishable, long lasting, cheap (when compared to ANSCO 130) and above all performs really well. What is there not to like?

Looking to extend my knowledge about this print developer ... please post your experiences with DS-14

I use DS-14. It lasts well, provides good quality and is easy to replenish as you say. I've not seen any disadvantage, and is a formula I will continue to mix up.

So folks reading this thread won't need to search for it, here's the formula for the paper developer, DS-14. Paper developer, not film developer. I copied all the material below (including remarks) from this posting by Gerald C. Koch.

​

DS-14 Paper Developer​

​

Sodium sulfite, anhydrous 12.0 g​

Ascorbic acid 6.0 g​

Dimezone S 0.2 g​

Potassium bromide 1.0 g​

Triethanolamine 5.0 ml​

Salicylic acid 0.5 g​

Sodium carbonate, monohydrate 30.0 g​

Water to make 1 l​

​

pH 10.4 +/- 0.2​

​

Use full strength and develop for 1-1/2 to 2 minutes at 20 C.​

​

Triiethanolamine can be obtained from various places that sell photochemicals or from www.thechemistrystore.com. Salicylic acid can be bought from a compounding pharmacy. It is not expensive. Both these chemicals are used as complexing agents to preserve the developer.​

​

I have personally used this developer and it is very good.​

​

All the Ryuji formulas should be in the APUG archives.​

Attached are some notes I copied directly from R.S.'s web site. It adds a little information, including alternatives to Dimezone-S (phenidone variants).

One note on the notes...

The last sentence doesn't make sense to me as written; I believe it should read "One workaround is to prepare the concentrate without any of these Phenidone derivatives, and add Phenidone or Dimezone immediately before use."

I'm sure that's what he meant. I just copied and pasted into a pdf.
