Regardless of when the snow coats the landscape, you need to change the standard settings on your camera to record the scene accurately. In an earlier post, I wrote about the importance of adjusting the exposure to be brighter and carrying an extra battery to enable you to shoot longer in the cold.
Another important control is White Balance. This setting (often labeled WB) adjusts for the color of light falling on your subject. Normally, when the sun is shining on my landscape, I set the White Balance to Daylight. But at higher elevations the light can have a strong blue cast. So you may want to experiment with either the Cloudy or Flash white balance choices. Both add a bit of yellow to the picture overall to counteract the blue light and make the snow look whiter.
