I just bought a circular polarizer filter for my camera and it's supposed to give you more saturated colours outside as well as finer definition of clouds. I tried a few tests outside today and it's looking pretty cool. One of the photos I got of a helicopter flying looked pretty good but looks even cooler if you run Picasa's contrast filter on it. This should hopefully make for some cool cottage photos at Alex's.
