What should I pay attention to when using digital cameras in winter?

The low temperature in winter has the greatest influence on digital cameras. In the sub-zero temperature environment, the battery will be dead soon, and its endurance is only half of that in summer. If you don't take many photos, it will automatically turn off the alarm. 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. The first thing is to pay attention to the warmth of the camera and spare battery: you can buy a camera case to keep warm in winter, or carry the camera and spare battery close to your body to keep warm with your body temperature. Secondly, save electricity reasonably: for example, use an optical viewfinder instead of an LCD screen, use an electric lens to zoom back and forth as little as possible, turn on the automatic shutdown function, turn off the wireless function, etc., and 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, which can be used in an emergency.

In winter, you will find that when you enter the room from the outside, the lens will be covered with water mist, and the camera will also be covered with water mist, and the consequences will be more serious. Moisture can damage the internal circuit of the camera.

In fact, the solution is that indoor water vapor will liquefy when it comes into contact with the camera surface at low temperature, so when we want to enter the room, we can first seal the camera in a plastic bag, so that when you enter the room, the moisture will condense outside the plastic bag, not on the camera and lens surface. In case the camera gets wet, don't turn it on in a hurry. You should leave it indoors for a while until the water evaporates, or you can blow it with a hair dryer, but remember to use normal temperature air.

Taking pictures in snowy days needs to protect the camera in all directions, because there are two situations that damage the camera in this environment: cold and wet.

The best solution is to choose a sheltered place to shoot or cover the camera with a waterproof cover to prevent snowflakes from falling directly on the camera body and lens. Once it falls, it can be wiped off with absorbent cotton or lens paper in time, or removed by blowing. When the temperature is low, don't blow directly with your mouth, because the hot air from your mouth will melt the snowflake and quickly frost and stick to the lens, which is even more troublesome.

When shooting a snow scene in the snow by photometry, 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.

The composition in the snow is beautiful, but the picture 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 for the front or vertical illumination of light to reflect the hierarchy and texture. Dead white will also make the snow scene dull, so 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.

Other anti-falls: In addition to the above-mentioned endurance and fogging, the camera surface will become slippery in winter because of the cold climate, especially for the metal case. When using it, be sure to equip the camera with a shoulder strap or wristband, and don't take photos directly in your hand.

Anti-static: There is another danger of dry camera in winter, that 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 act as a "ground wire" before taking the camera.

Keep warm: Take photos outdoors for a long time in winter. Pay attention to your own warmth while protecting your equipment. Try to wear light and warm clothes to facilitate activities. It is best to use waterproof fabric to shoot clothes in snowy days to avoid melting and wetting clothes. Gloves are also suitable for photographic gloves that are convenient to operate buttons. Of course, hats and scarves are needless to say, and they can also be used as a cold shield for cameras when they are not worn.
