Tri Seasonals

The most difficult part of shooting in the winter is all of the snow. It is difficult to get to your exact locations since there is probably 2 feet of snow on the ground. It is hard to remember your exact location of the shot because there is snow covering almost everything. Also, since it is so cold outside, your hand is cold and shaky and you do not get a clear photo.
