Cold weather causes problems for photographers. For some, this may be a trick. For others, a warning.
*** BEFORE you enter a warm house, car, or building, put a plastic bag on the camera while it is in the cold. That keeps condensation off the camera, lens, and electronics. Remove the bag after 30-60 mins when the camera is room temp. Then store the camera open to the air. Do NOT store in a closed, lens pouch, or bag. The fungus will grow inside and then you are in big trouble!
Clear plastic bags include a dry cleaning bag and a rubber band.
Keep 1-2 bags in the camera or rubber band on a tripod. Don’t leave home without one!
If you screw up and have no bag, take off your coat outside, wrap the camera, then go indoors.
If you really screw up and bring the camera in a warm house or car, immediately go back out or into an unheated garage, let it get cold again, maybe 10 mins, and then bag it and go back in.
If my camera gets rained or snowed on, I carry a towel in the car to wrap the camera in the towel and then bag the towel. If I’m shooting outdoors, I go to the car to get the towel before coming in or leave the camera outside on a porch, go in, get a towel, and then come out. When it warms up inside, maybe 1/2 hr because the towel is on, then I dry it as best possible without taking the lens off and leave it on a table to dry overnight. Then store it in an open camera bag or open lens pouches until next time.
