1. Cold climate protection
Modern cameras are usually well protected against the cold, but there are still a few things you can do to prevent moisture damage.
If it’s snowing make sure your camera and lenses are covered up or in a waterproof bag. Try not to keep your camera too warm as whipping it out for that once-in-a-lifetime shot will cause condensation on the lens, giving you a foggy image. Camera batteries also lose their charge in cold conditions, so keep any spare batteries inside your jacket.
