Hi Alan,
Not a CPL expert, but just attempting a brief analysis. To compare, I
clicked each link in succession, opening them in the same window in IE. I
don't think there's much colour difference in the blue saturation really;
solely based on these two examples, I think it's too subtle to warrant
paying the extra money for the B+W. Like William, I noticed the B+W's poorer
flare control, it's the most obvious thing when you're flicking between the
two images (back + forward buttons) in IE (with the next picture in the
exact same position as the second, so any 'movement' is a difference in
image quality). The second thing I noticed was in the little bit of shadow
detail in the snow on the roof in the bottom left. I don't think that was
the result of the polarising effect though. What it appears to be (to my
untrained eye) is that the B+W seems to be costing a bit more light (perhaps
1/3 stop?). If this is the case, that's why the sky in the B+W example looks
a bit darker? From the results, I'd favour Hoya. Perhaps try a few other
shots? Maybe the cliche person through the windscreen of a car, or koi in a
pond (unless you've got really lazy koi, it'll be hard to get them in the
exact same position I reckon..), or maybe just a lake with some sky in it?
Just some thoughts.
Regards, Ryan
