Winter photography tips

Winter is nearly done, but there will probable be more snow.  Many of the spring snowfalls are heavy and cling to trees, making for beautiful images.  There can also be ice coating trees and other plants, this also makes for very interesting images.
To keep your camera dry you can use a large Ziplock bag (I like the 2.5 gallon size) to protect your gear.  Also batteries don't last as long in the cold.
If I am outside , in cold weather, for a long period of time, I place the camera in the Ziplock bag when coming into the warm indoors.  Place the camera, lenses, etc. in the bags and force as much air out as possible, while zipping them.  Bring them inside and let them warm up for a couple hours.  If you bring them indoors, without doing this, the gear can fog over and moisture can condense, possibly causing problems down the road.  By putting the gear in a sealed bag, the condensation should be on the outside of the sealed bag, not the camera.
