Matters needing attention in using cameras in winter

Why does it not take long for the camera to run out of power in winter?

The biggest influence of low temperature in winter on digital cameras is battery capacity. In the sub-zero temperature environment, the battery will soon be dead, and its endurance is only half that of 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 also two ways to extend the use time of the camera during shooting. First of all, pay attention to the warmth of the camera and spare battery: you can buy a camera cover to keep warm in winter, 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, use optical viewfinder instead of LCD screen, use electric lens to zoom back and forth as little as possible, 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 pictures, just in case.

Why is it foggy when the camera comes into the room?

Friends who wear glasses in winter should have this experience: after entering the room from the outside, water mist will form on the lens, and this problem will appear in 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 with the low-temperature camera surface, 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 outside the plastic bag, not on the camera and lens surface. Don't start the camera in a hurry to avoid getting 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 problems 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. Taking pictures in snowy days needs to protect the camera in all directions, because there are two situations that can damage the camera in this environment: cold and wet.

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 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 also 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 layering 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.

Is there anything else to pay attention to?

Anti-fall: In addition to the aforementioned problems of battery life and fogging, the camera surface will become slippery in winter because of the cold climate, especially the metal case. Therefore, the camera must be equipped with a shoulder strap or wristband when it is used. 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 easy to generate static electricity, you'd better touch something that can be used as "ground wire" before taking the camera.

Keep warm: Take photos outdoors for a long time in winter. While protecting your own equipment, you should also pay attention to your own warmth. Try to wear light and warm clothes to facilitate activities. On 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. You can also wear the camera as a cotton-padded jacket when you are not wearing it.
