Batteries
Ensure the batteries stay warm for optimal camera performance in extremely cold conditions. Your camera will operate effectively as long as the batteries are functional, but be aware that cold weather accelerates battery drainage. For winter shoots, it's advisable to carry multiple sets of charged batteries, with a preference for types that perform well in low temperatures. Store extra batteries in a pocket within your jacket to maintain their warmth, and consider adding a chemical hand warmer to the pocket for added heat. Regularly rotate the batteries between the camera and your warm pocket to sustain their performance.
Tripods
Avoid touching a cold tripod with your bare hands, as it can be uncomfortable. To address this issue, some photographers opt for tripod leg warmers, which are available from various manufacturers. Alternatively, you can improvise by using plumber's pipe insulation for the tripod legs. Crafting your own tripod leg covers is a budget-friendly option—utilize foam pipe insulation and hockey tape (known for its cold resistance) for an effective solution under five bucks. Exercise caution to avoid forcing the tripod into the snow, as this can lead to damage.
When shooting in snowy conditions, employing a lens hood is beneficial. It helps prevent issues caused by falling or blowing snow on the front element of the lens, ensuring clearer and unobstructed shots.
