In about a week I will have one of my few chances to get a photo of Japan's Mt. Fuji. Summer is not a good time to be photographing the sacred mountain. Your chances on any day in the summer of getting something decent are slim due to clouds and thick haze. Because of this, I did not schedule any photography stops. My best chance will be on an early morning shinkansen (bullet train) heading south out of Tokyo. I will therefore have to shoot through the window of a (very) fast train.
What's the best technique? Do I use a polarizing filter to reduce the window glare?
