You can find 400 speed Fujicolor pretty reliably again, at least around me. 3 pack of 36 exposure cassettes for $25 at B&H. This is my first roll of it but it feels a lot more like their recent 200 with more grain than it feels like an iteration on the Superia style.
There's a sizeable faction of photographers who loathe Superia for its green-cast shadows, especially folks who do portraiture, but I think these people are cowards. The muted color response that New Portra has brought into vogue (leaving any punch to be added in digital post) also made Superia feel like a stock out of time. If you want rich, bold colors now you can still shoot stunt lomo stocks or Ektar, I guess.
None of this is to say it's bad. At half the price of CineStill's 400Dynamic (and with an antihalation layer even!) there's nothing to lose sleep over. But it's getting a lot closer in character to Kodak's UltraMax 400 and.....we already have that. It's called Kodak UltraMax 400.
I didn't squeegee or finger-squeegee these, enjoy the little water spots/calcification all over. This is my fault, and not the film's.
