Re: One year old DS-2 not dead, DS-5
Ryuji, thank you for your detailed answer!
I know that DS-2 has to be used fresh, I was just curious, how it performs or is it still working after one year.
So we are expecting new developer from Digitaltruth.

I have quite a few EFKE Ortho film to develop. It's quite contrasty and I must low down the contrast.For that type of applications, I use DS-10 diluted 1+2 at 25C. But unless you are using pinhole or other cameras that are easier to work with orthochromatic sensitization, tonality would be much better if you used ordinary pictorial films...Last month I tried your DS-2 developer, which I mixed ONE! year ago. 2x concentrate prepared with distilled water was stored in small 100 ml glass bottles filled to the brim. On my surprise developer after one year was not dead, but it was not as potent as already prepared. With prolonging the development time for 50 % the Ilford PAN 100 and EFKE KB100 looks pretty normal except grain is a little bigger.While DS-2 may keep better in certain cases, I do not endorseSo I think it is not true that this developer dies very quickly. I routinely use it one month old and is as good as new.
