Velvia 100 is my favorite film for moonlight, unless I want Provia 400x for more speed. I have not had the green shift 50 sometimes gives (though I'll say that I strongly prefer 50 for almost every other application). I have only done exposures up to the 4 to 5 minute range. Under a full moon on green grass, 3 minutes at f4 is my usual starting point. As expected, Velvia 100 results in more saturated colors (especially reds and browns) than Provia.
