Take Care of Your Camera
The first, and most important, thing that you need know is how to take care of your camera when shooting in the cold. Keep your camera in its case, with extra towels around it. Do not breathe on the screen. This will create moisture. Reintroduce your camera to warmth slowly. Let it sit in your garage for a few hours, then bring it in. Remember to also bring an extra battery. Camera batteries tend to wear out faster in colder weather.
Increase Exposure
Set your camera to "snow-scene mode" while taking photographs with snowy backgrounds if your camera is a point-and-shoot. Otherwise, there will be a setting on your camera that will allow you to manually adjust the exposure. Adjusting the exposure will create lighter or darker photos, depending on whether you are looking to increase or decrease the exposure. In this case, you will need to increase it.
Adjust White Balance
Using your camera's "Auto Balance" tool will automatically adjust white balance without you having to worry about it. Choosing to manually adjust the white balance on your camera, however, will improve the color and contrast of a picture, especially when you are frequently transitioning from the indoors to the outdoors.
Action Shots
If you plan on taking a lot of action shots, you must set up your camera so that it will have a faster shutter speed. Generally, a shutter speed of 1/4000 is best for action shots. In order to compensate, you will need to change your aperture to a number that will work well for these pictures. Setting the aperture to f/11 or f/16 will work. Increase the ISO to create better shots in the snow.
