Cameras used outside in the winter are prone to condensation.
When a cool object is put into warm air, condensation forms on the object. This buildup of moisture can easily rust or mold the internal elements of a film-based or digital camera body, a camera lens or a camera flash unit. When moving from cool air conditioning or cold outdoor winter conditions to a warm, humid environment, condensation will occur.
Instructions
1. Keep the camera warm when in cool conditions. Place it under your coat, or cup it inside your hands while wearing thick, insulated gloves. Never let the camera cool completely to the ambient cold air temperature.
2. Wrap the camera in newspaper or a plastic food storage bag when preparing to leave the cold environment.
3. Seal the plastic food storage bag so the condensation forms on the interior lining of the bag, not the internal components of the camera, lens or flash unit.
4. Move to the warm environment. Allow the camera to stay in the newspaper or plastic bag until it warms to the new surrounding temperature.
5. Remove the camera from the protective cover carefully. Look it over and make sure it is dry before turning on the power. Wipe down the surface of the camera with a microfiber cloth, removing any visible condensation.
