That's awesome you scan your own negatives. Something I've wanted to try but haven't because I don't have a nice digital camera. I just get back TIFFs from my lab and sometimes don't change anything, and if I do, it's pretty much just adjusting the tone curve before exporting to a more compact format. Doing all the color editing and stuff sounds pretty stressful to me though lol. Probably harder to perfect than shooting on film by itself.
I think the vision 3 shots you have posted so far are a tiny bit more muted vs this porta shot, and have a bit of a pinkish "Etheral" vibe to them. If that makes any sense haha.
