This thread reminds me of a question I've thought about asking for a while -
can anyone recommend a good photography video that would be available in the
UK, preferably that includes developing/printing?

Subject: Re: [OM] Re:OT Polarizers (was Linear
polarizer & OTF)
I noticed some years ago that if a pair of polarized
sunglasses and a
linear polarized filter were turned the right way, the light
got very
dark and everything had a "black light" effect or glow to
it. Haven't
tried this with a circular polarizer. Does a polarizer not
affect the
ultraviolet wavelengths?
I recently borrowed a video Series from the library called
Creative
Outdoor Photography w/ Frans Lanting and Galen Rowell. In
it is
demonstrated a theory of color photography proposed by
Edward Land in
1959 called the Retinex Theory of Color Vision.
He photographed the same shot with b&w film using two
different filters
(I don't know which) then printed each resulting negative
onto one sheet
of color paper (using a red filter with one of the
negatives. (Again, I
don't know which neg.) The result was a full spectrum
photo.
The point, in the video, was that our eye sees differently
than film
*sees* light. This should certainly be considered when
viewing through
a viewfinder while using a polarizing filter. I'm just not
sure of how
much and which way!
