These Gunnysack Creek images were taken during the last Alaska Photo Workshop on our trip to the Maclaren River Lodge.
The problem with adding a polarizer to a wide angle lens is twofold. One, vignetting becomes an issue if your polarizer is to think. Try to purchase one that is thinner so as to avoid this. And Two, when you include much of the sky with a wide angle with polarizer the sky becomes polarized in one spot and usually by the edge of the frame is less so. To deal with this issue simply include only small portions of the sky in your photograph.
