If you're in the southern hemisphere this might be the least timely post of all time, sorry. For the rest of us northerners in cooler climes, there are a few things to keep in mind for photographing in the snow:
1. Protect yourself. Aside from the usual layers, boots etc, you'll probably need some gloves, ideally that are light and flexible. I use simple woolen gloves but keep my hands in pockets a lot too.
2. Protect your gear. Depending on whether your camera is weather sealed, if it's still snowing heavily you might need to a cover or rain sleeve. I use this one: Optechusa.com. Using a lens hood too will keep falling snow off your lens and help to prevent glare in brighter conditions.
3. Over-expose. With mostly white in a scene your camera tries to average things out, turning bright whites into grays. Either use manual controls or exposure compensation to keep things bright.
4. Look for contrast. Darker figures, ideally surrounded by a background of snow, will stand out and provide a point of interest.
5. Take extra batteries. Colder temperatures mean less battery life.
6. Get out there! It's easy to be put off by the cold and stay inside but who knows how long it will last and if other photographers and staying indoors then there's more chance that your images will stand out.
