Hi Warren.
Thanks for the advice.
I guess I'm not sure exactly how a polarizer works, other than cutting
glare... time to do a bit of research.
Using a graduated ND to darken the top of the shot would work but I usually
use the 18mm for distorted close-up shots of snowboarding so a graduated
filter might not be ideal.
I've been told that a rule of thumb for shooting people on snow is to meter
the snow and then overexpose 2 stops so you get details in the(much darker)
people. I'll probably shoot a roll with no filter and see how it comes out.
