Your methodology does not warrant such a conclusion.
PE was very clear in his argument that RA4 is essentially a development to completion process. This goes entirely against your theorizing.
Your methodology does not warrant such a conclusion.through my experience that controlled temperatures (35C) will be better because that there is unlikely to be any consistency with prints not made where a technique not kept within close professionally advised temperatures.
+1PE was certainly the appropriately acknowledged expert here on RA4 processes. If he said he processed at room temp in trays and was satisfied the process worked as intended that’s good enough for me. That said, I’ve always used (and will continue to use) the recommended temperatures- just habit and not wanting to wait!
Most folks who still work in a darkroom shoot a lot of black and white. LFPF members shoot formats that no color film exists.
The cost of color sheet film is breathtaking. Biggest I can go in color is a 4x5 negative for enlarging. I have 10 sheets of 8x10 Portra, I want to contact print. I love contact prints. I have 11x14 cameras but no way I'm in the market for color that big. There's a limit, I hope to my Insanity
I'm with You my friend!!Serious amateurs have no bounds with insanity. Get in either the clown car or the lunatic trolley.
That's a beautiful setup, whole space looks fabulous!!Finally got my Nova set up
That's an amazing darkroom!Finally got my Nova set up
I did some testing today. I shot some photos up close of a gray card, with a big studio flash. Ektar 100 and Portra 160. Anyway I made some prints today using Kodak's filter finder kit from the 70's. These tests confirmed what I suspected for filtration (filter pack) for the Ektar that I had made some earlier prints
What surprised me was the filter pack for the Portra 160 was identical.
Makes it easy to jump from a Portra offering to Ektar. Nice.
Not really in my experience. Prints come out just fine within the normal range of room temperatures in my former darkroom (ca 16C up to ca 28C).
Finally got my Nova set up
Not sure which photo you were referring to, but I think it is the curved stainless steel tray.What roller/machine is this? Is it for rocking chemistry back and forth with a print inside?

It is a Mitchell / Heath "Color Canoe" for up to 16x20 inch sized prints. One tray for all of the chemicals, so you pour in, rock it back and forth then pour out, rinse and then the next solution etc. At this size it is a bit cumbersome to lift and pour, but not too bad. Fumes can be a bit of trouble as there is so much surface area for it to off gas from. If I use it, it is generally at room temp RA4 for 2min. The cooler temp has a bit less fumes. For some reason I do want to collect the other sizes that were available way back when, 8x10 and 11x14... I know of one close by, just haven't managed to convinced the guy to let it go yet.
Today I mostly use the Printo I picked up a little while back to do my color work, so this tray doesn't get much use.
Thanks! Yea that’s the one I was talking about. Speaking of fumes, how bad can they be in a modestly sized apartment?. All my rooms have windows, bathroom has a vent and I keep an air purifier around. I’m just looking to start printing 8x10s or 11x14s at home. Would love to have a printo or RCP20 but might have to just do drums until something comes along .
This machine can process RA-4 paper? I’m looking for any at home/studio options for printing RA-4 and I’ve come across photos of it several times but I can’t figure out how it works. Does the paper get carried by rollers?
