The combination of snow on the ground, very cold temperatures, and low light make for excellent photographic conditions, if you can bear to be outside.
I exposed this view of New England Central 3476 shortly after sunset in Palmer, Massachusetts.
The snow reflects light from below, thus providing greater illumination of shadow areas that under ordinary conditions would be underexposed at this time of day.
Cold temperatures and clear overhead conditions result in a inversion effect, which traps particulates and other airborne impurities that acts as a light filter resulting in a scene with more red and magenta spectrum than normal.
This effect is intensified at sunset because the sunlight has to pass through much greater amounts of polluted atmosphere because of its relative angle to the ground.
To make the most of these lighting conditions, it helps to set the camera white balance to ‘daylight’, since ‘auto white balance’ while tend to cancel out the effect of the rosy lighting conditions.
