All your scans are way to dark.

Yes I agree -- need a little 'adjustment' in Levels or Curves to lighten dark shadows.

I'll give it a try this weekend. These are all straight out of the scanner with no intervention on my part.

We're seeing the heavy magenta color shift that was typical of many labs with Velvia. Pro labs often processed Fujichrome slightly differently than Ektachrome in the same processors/chems for that reason. The easiest (and most fun) way to adjust this is with NIK, which simply adjusts visually and non-destructively with sliders rather than requiring direct use of Photoshop or Elements.
