Re: dissolving phenidone

Phenidone is only slightly soluble in plain water. Good thing we don't use a lot in most developers. It dissolves much more readily in alkaline solutions. It is also soluble in 91% Isopropyl alcohol (drug store item in my country, rubbing alcohol (drugstore item and usually 70% methanol), glycols, g...

Re: Percentage solutions

OK, revealing my real age, Jason Schneider used to recommend using a sulfite solution for diluting Rodinal, his "precise measure" was a level "Chock Full of Nuts" coffee scoop.

[Forgive me for sticking this in the FILM development forum but I don't see a forum on black and white PAPER developers.] What are the common "best" percentage solutions for developers additives, e.g. 10% Potassium bromide 6% Sodium Carbonate 0.2% BZT (benzotriazole) Am I missing any, what about hav...

Re: C-22/C-41 Cross Process - Is It Possible?

You will not get true, pure colors but hey the film is roughly 40 years old, right? C-22 uses CD-3 and C-41 uses CD-4. I would try processing at no more than 75 deg. F. at around 15 minutes for a first try (you don't day how much of this film you have). Expect a bunch of crossover, too. If you Googl...

Re: Omega D2

Steve, did you ever get a reply to this offer? I think the D2 is a fantastic piece of kit, and no, I don't need another one, I already have a D2, a D3, and a D5 and when I brought the D5 into the house my wife finally gave me "the look". I posted here merely to give this offer a bump.

Re: Developer Dilution - How Does it affect your negs?

You can add higher speed (in some developers). Some developers never gave the film's full "box" speed at stock but did give the higher speed (as rated) when diluted 1+1 or 1+3. Microdol-X and Perceptol for two that come to mind. Just my two cents.

Re: Acufine / Tri-x - 1 stop push dev time?

I'm pretty sure Acufine is still Acufine but Tri-X (now 400TX) is not the same stuff we were pushing 20-30 years ago, Tri-X 400 and is surely not the stuff I was using in the late 70's Tri-X 5063. The Acufine data sheet says rate new Tri-X at EI 1000, calls for 5 minutes (that's only a 1/3 stop off)...

Proper Reflective Metering for Color Transparency Film

Use an incident light meter. You use it to measure the light falling on your subject, not reflected, and that means that the meter and operator can't be fooled by subjects with unusual reflectances.

In my (crowded) home darkroom I have a D5/MG600 head, a D3 with a Variable Condenser head, and a D2 I am rebuilding. I am replacing the bellows on the D2, not for damage, but because the seam came unglued. On inspe...
