So I've done some research, and seeing as room temp RA-4 is certified as being "good" by PE, decided to do start working toward getting an RA-4 setup to do some color printing fun. It'll be a bit painful since I don't have a color head on my enlarger, but under lens filters (either the CMY ones stacked, or RGB multiple exposure) sound reasonable, even if a bit annoying.
I want to do room temp RA-4 in trays. I have a few questions:
1. I've found the Kodak RA-RT Replenisher on Amazon of all places, but I can't find an alternate source for when that seller inevitably stops or jacks up the price. Is there a better source that I can rely on in the future?
2. I saw Freestyle selling "Silver Pixel" branded chemicals that sound similar to Kodak's. Are they the same? Is it safe to use their blix in this process? I can't find any source for Kodak blix
3. Any tips for doing tray processing in darkness? Is there any minimal safelight that might help me with locating the trays and such? Is it safe to expose to light after stop bath or should I wait until blix?
4. Is this process compatible with the reversal process for doing RA-4 printing of slides?
5. My nominal room temp is around 72F. Any adjustments needed? The times I've seen quoted for 68F is 2' for dev, 30" for stop, and 2' for blix. Not sure how sensitive this process is to color shifts, but I do have experience with E-6 and C-41
6. How much capacity can I get out of the chemicals? I see for tank processing, you'd normally use them one shot.. but in tray I can't find any referneces
7. I've heard the starting filter packs for this is different from normal RA-4 processing. What is a good starting filter pack?
8. Any other tips for doing this process, as someone somewhat experienced with B/W printing, but never having done full darkness printing?
