Sirius - no color film ever represented real world color as our eyes see it. As far as Velvia goes, it could differentiate certain hues of brilliant green or purple better than any other film, but only if you worked within its realistic contrast range, which people seldom did, and just wanted to go hyper with it. Astia was the most color accurate overall. I once shot an old pre-E6 Agfachrome 50 which would render warm tones better than any film since, and would even capture fluorescent lichen and algae colors, but couldn't yield saturated Spring greens. Neither could classic ole Ektachrome 64; but it would do sage greens and bluish neutrals better than any current film. Every single color neg film ever invented has certain serious color repro issues. There is no silver bullet, never will be. "A man has to know his limitations". But I have little patience for the current craze to just go hog wild overboard with every silly app and so forth. That's their right; but I'll never personally call it photography or go out of my way to view it.
