=46rankly, I doubt that that's what Joe had in mind.  I bought the
warming/cooling one when Porter's was remaindering them several years
ago and have never used it.  A bit too gimmicky for my taste, though I
suspect some advertising photographers of using the warming setting
when they can't get that coveted pre-sunset look any other way.
Knowing something of how Pop Photography worked in Rothschild's day, I
suspect that--though it was a novel idea that might have caught his
interest for that reason--he was told to write about those filters
because they could get an ad contract for them if he did.  Perhaps
things haven't changed much.

But a regular (non-color, or neutral-color) polarizer will darken
skies and make some colored object look more saturated by cancelling
out reflective "haze" that is polarized at 90 degrees from the filter
setting.  That's presumably what you're after and what I imagine Joe
was referring to.
