Many, many times I have heard from people how they photographed something during a snowfall and it turned out really dark and the snowflakes were not visible.
First of all, your camera turns everything medium gray because that is what a meter does. So to turn the snow white, go to the compensation dial and plus up the exposure to overexpose the scene. This will make the snow white.
Photographers looking for a challenge should try their skill with GP Anderson's display at 414 3rd St. S.W. in Wadena. Anderson has added computer animation to the display synched with music. You can tune into the radio station with the songs and watch the lights.
The tough part is being in the right place at the right time. With certain songs you need to be ready with your camera at certain locations at the display.
