While out in the tetons on our photography workshop, it snowed. Then it snowed some more. After that, it snowed a little more. Over about a two and a half day period it snowed over 30". So, we got our fair share of photographing while it was snowing. If you didn't mind standing outside and getting snowed on, there were a lot of photographic opportunities to be had. Wildlife was the biggest of those opportunities.
You encounter a few problems when photographing in the falling snow. Depending upon the amount of snow falling in between you and your subject it can cause your autofocus system to get confused. It can also create a layer of "haze" between you and your subject. The first one you can deal with in a few ways. You can just use your autofocus system and hope it is smart enough to figure it out, which might cause you some lost shots, or you can simply switch to manual focus. The problem with autofocus is it's going to, sooner or later, decide to focus on falling snow instead of your subject. There is almost a guarantee this will happen when your subject is doing something super interesting, or has moved to a nicer background ;) The second problem..haze. It can't really be fixed, but can be helped out a bit by using the "dehaze" slider in Adobe Lightroom CC. This slider is pretty much magic and can knock down that haze in your image by a great deal.

This is one of the moose that came to hang out with us at the ranch. There were three of them. They showed up everyday. Usually, when the ranch fed the horses, the moose showed up there to "share" breakfast with them.
