portra 400 is god-tier for certain landscape situations......gotta know when to show dem Portra golds, plus 400 is super-forgiving on exposure almost as much as Tri-X.
it's not a be all end all I usually use Fuji 160ns for greens, Provia 100f for blues but in a pinch Portra 400 can pull off landscape.
It's strength is skin tones, remember, so if your scene is dominated by skin tones, then you're set, and this includes winter foliage.
