Matters needing attention in using cameras in winter

why does the camera run out of power in winter?

the biggest influence of low temperature in winter on digital cameras is the battery capacity. In the sub-zero temperature environment, the battery will be dead soon, and its endurance is only half of that in summer. If you can't take many photos, call the police and turn it off automatically. So when shooting outdoors in winter, the most important thing is to bring a spare battery, just in case. Of course, the higher the machine, the stronger the frost resistance.

there are two ways to extend the use time of the camera during shooting. First of all, we should pay attention to the warmth of the camera and spare battery: you can buy a camera cover in winter to keep warm, or you can carry the camera and spare battery close to your body and keep warm with your body temperature. Secondly, save electricity reasonably: for example, replace LCD screen with optical viewfinder, zoom back and forth as little as possible with electric lens, turn on automatic shutdown function and turn off wireless function. So you can take as many photos as possible. Another trick is to take out the battery and cover it for a while when there is no power. You can usually take one or two more photos in case of emergency.

how did the camera get foggy as soon as it was brought into the house?

friends who wear glasses should have this experience in winter: after entering the room from the outside, water mist will form on the lens, and this problem will happen to the camera, and the consequences will be more serious. Moisture can damage the internal circuit of the camera.

This situation is actually the result of indoor water vapor contacting the camera surface at low temperature, so when we want to enter the room, we can put the camera in a plastic bag and seal it, so that when you enter the room, the water vapor will condense on the outside of the plastic bag instead of the camera and lens surface. Don't start the camera in a hurry in case it gets wet. You should leave it indoors for a while, and then use it after the water evaporates. Or you can blow it with a hair dryer, but remember to use normal temperature air.

what should I pay attention to when shooting in snowy days?

Snow scene is the most unique landscape in winter, and it is also a subject that many netizens must shoot in winter. It is necessary to protect the camera in all directions when taking pictures in snowy days, because there are two situations that will damage the camera in this environment: cold and humidity.

It is best to shoot in a sheltered place, or cover the camera with a waterproof cover to prevent snow from falling directly on the camera body and lens. Once it falls, you can wipe off the snow with absorbent cotton or lens paper or blow it away with air. When the temperature is low, don't blow directly with your mouth, because the hot air from your mouth will make the snow melt and then quickly frost and stick to the lens, which will cause more trouble.

photometry: when shooting a snow scene, the picture is often dark, which can't show the whiteness and purity of the snow. This is mainly caused by the photometric principle of the camera. In addition to using the pure manual gear, ordinary netizens can improve it by adjusting the exposure compensation, which is generally "white plus black minus", that is, when shooting a large area of white, the exposure compensation is appropriately increased.

composition: it is beautiful to have a dirty look, but the picture taken is too monotonous and not necessarily beautiful. Plants, buildings or humanities can be added to the snow scene to enrich the color of the picture. In addition, because the snow itself is white, it is easy to reflect light, and it is difficult to reflect the hierarchy and texture when the light is direct or vertical. If it is dead white, the snow scene will become bland, and it is best to shoot with side light, backlight or side backlight; Similar to portrait photography, the light is usually soft after sunrise or before sunset, so you can try to choose these two time periods to shoot.

what else should I pay attention to?

anti-fall: in addition to the aforementioned problems of battery life and fogging, the camera surface will become slippery in winter due to the cold climate, especially the metal case. Therefore, the camera must be equipped with a shoulder strap or wristband when it is used, and don't take photos directly in your hand.

Anti-static: Another danger of dry camera in winter is static electricity, so if you wear a lot of clothes that are prone to static electricity, you'd better touch something that can act as a "ground wire" before taking the camera.

keep warm: take photos outdoors for a long time in winter. While protecting your equipment, you should also pay attention to your warmth. Try to wear light and warm clothes to facilitate activities. In snowy days, it is best to waterproof the fabric of clothes to prevent the snow from melting and soaking clothes. Gloves are also suitable for photographic gloves that are convenient to operate keys. Of course, hats and scarves go without saying. When you are not wearing it, you can also wear the camera as a cotton-padded jacket.
