Batteries + cold weather doesn’t equal true love forever.
If you’re planning to take photos during a cold day, make sure you pack tons of batteries, and keep them in a warm place. The temperature has an annoying habit of sucking them of their energy. Not what you want to happen when you’re outside shooting pictures. Also, keep your camera tucked in your jacket—preferably close to your body—to keep the camera warm. You’ll be glad you did.
