It does seem contradictory, yes. If the film is not very sensitive to
blue,
then blue skies come out dark. (Or maybe I have it backwards. But then, if
a
film is not very sensitive to light, then the whole scene comes out dark,
right?) Thus, no need for a polarizer. Regardless, To get rich blue skies
I
don't need a polarizer as I have had to with Ektachromes (100, 64...), and
scenes I've shot in shade have come out neutral. Fow whatever reason
Ektachrome scenes in shade come out blue... I don't know, but for me they
have. Again, this is with the old Ektachrome 64 and 100 films... in 4x5.

If Ektachrome 100GX is as fine a resolution as Provia 100F, has all of its
other fine characteristics, and is available in 4x5, then I'll someday try
it. Thanks for the link; I'll take a look.
