[filmscanners] Re: Kodachrome green / scanner colorimetry

One suggestion that I found with Kodachrome when I was having problems
with the color response with my good ol' HP S-10 and S-20 scanner.  I
could never get the color rendition correct via levels or curves of
individual channels without considerable work.  However, I found I was
able to make a ballpark correction by going into HUE in Photoshop, and
moving the top slider around a bit for each color required (via the drop
down menu).

A little unorthodox, but it worked.
