Re: Septic & well water

What' type of domestic water well do you have? Most houses using well water have a well casing of steel or plastic pipe that is sealed above the aquifer and below surface water. Bentonite clay or hydraulic cement were the usual sealants. [Father was a well driller.]

Re: Datatainer labels

Sharpie comes off very well with both PEC-12 and Goof-Off (not the citrus based stuff). Lighter fluid and Coleman Stove fuel would probably work also. And you can always overwrite permanent marker with a dry erase marker and it usually comes off.

Re: Durst 609 spare parts wanted

Steve, the piece that's broken appears to be just a "cup" for ease of printing uncut rolls of negatives. I'm sure such a thing could be 3D printed, and it would be best removed if not replaced to avoid scratching negative strips. Link to a manual? https://web2.ph.utexas.edu/~yue/609/Durst609.html da...

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: 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: 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.
