Cold Weather Shooting Means Extra Batteries

Another thing the pros have learned is that digital camera batteries don't last nearly as long in cold weather. So if you're going out shooting in the snow, you'd better bring at least one or two backup batteries for your camera or it could turn into a very short shoot.

Extra Batteries Are a Shoot Saver

I go out of my way to avoid using flash (I'm one of those natural light freaks), so my batteries last a good long time, and I seldom have to change batteries during a shoot. However, I have at least one backup battery for both of my cameras, and although I don't use them that often, when I have needed them, they've been a shoot saver big time. If there's a must-have accessory, it's an extra battery.
