Wow, a lot to catch up on. So, I don't do optical prints, but the only film I have trouble color correcting (I do DSLR scanning, and correct the color in Photoshop using curves) is when it's vastly under exposed, vastly over exposed, or when using ECN-2 film (Cinestill). I've not noticed any cross-over color, though I would assume the exact development and resulting curves is probably a bit different. This is easy to correct while scanning though. Only now (thanks to a sous vide machine) do I have a good setup for fairly precise temperature control. Beforehand with normal C-41 processing, I had way too many negatives that did have color casts, under development, washed out colors, and artifacts (stripes etc, though this may have been from cinestill processing). Stand development, I can load the tank, pour in the chemicals, and then go watch TV for 20 minutes. My process is not quite just stand. C-41 dev temp is at ~63F/17C, agitate for first minute, and agitate once after 20 minutes. Develop for a total of 45 minutes (or up to 47 when the chemicals start to get weak). I blix etc as normal.
I'm about to be traveling, but I plan on whipping up a new batch of C-41 when I get back, and doing several test strips with a color chart to actually measure what the effects are objectively. I'll make sure to report about it here. I'm sure it probably will vary some depending on film stock too. I also have another thing I'll do a write up on called "x-pro reversal". Basically processing E-6 film in C-41 chemicals and producing positives. I love experimenting with new processes in development.
I have some images attached as examples for stand development. Note I'm still learning how to best do color correction with curves. I can provide raw negative scans if anyone wants to further analyze them
