Digital camera winter use guide

A digital camera is a camera that uses an electronic image sensor to convert optical images into electronic data. It is different from traditional film cameras that record images through chemical changes on the film caused by light. Below I have compiled a guide for using digital cameras in winter, I hope it will be helpful to everyone!

1. Why does the camera run out of power after a short time of shooting in winter?

The impact of low temperature in winter on digital cameras The biggest thing is the battery power. In sub-zero temperature environment, the battery will lose power quickly, and the battery life is only half of that in summer. It will alarm and shut down automatically after not taking many pictures, so when shooting outdoors in winter, the most important thing is Bring spare batteries, just in case. Of course, the more high-end the machine, the stronger its frost resistance.

There are two ways to extend the use time of the camera during shooting. The first thing is to keep the camera and spare battery warm: you can buy a winter camera protective cover to keep warm, or you can carry the camera and spare battery close to your body and use your body temperature to keep warm. The second is to reasonably save power: for example, use an optical viewfinder instead of an LCD screen to view the view, 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., so that you can take as many photos as possible. Another trick is to run out of battery. When it automatically shuts down, take out the battery and cover it for a while. You can usually take one or two more pictures, which can be used in emergencies.

2. Why does the camera fog up as soon as it is brought into the house?

Friends who wear glasses should have had this experience in winter: after entering the room from the outside, the lenses will fog up. The camera will also be troubled by the formation of water mist, and the consequences are more serious. The moisture will cause damage to the internal circuitry of the camera.

In fact, this situation occurs because the water vapor in the room liquefies when it comes into contact with the low-temperature camera surface. So when we want to enter the room, we can first put the camera into a plastic bag and seal it, so that when Once you go indoors, moisture will condense on the outside of the plastic bag instead of on the surface of the camera and lens. If the camera gets damp, don't rush to turn it on. You should leave it indoors for a while and wait for the moisture to evaporate before using it. Or you can blow it with a hair dryer, but remember to use room temperature air.

3. What issues should be paid attention to when taking pictures in snowy days?

Snowy scenery is the most unique landscape in winter, and it is also a must-have subject for many netizens in winter. When taking pictures in snowy days, you need to pay more attention to the camera. All-round protection, because two conditions that cause damage to the camera exist in this environment: cold and wet.

It is best to choose a covered place to shoot or put a waterproof case or other protective gear on the camera to prevent snowflakes from falling directly on the body and lens. Once they fall, you can use absorbent cotton or lens paper to remove the snowflakes in time. Wipe it off or blow it off with air. When the temperature is low, never blow it directly with your mouth, because the hot air blowing out of your mouth will melt the snowflakes and quickly form frost and stick to the lens, causing even greater trouble.

Metering: When shooting snow scenes, the picture will often appear dark and the whiteness and purity of the snow cannot be expressed. This is mainly due to the metering principle of the camera. In addition to using pure manual gear, ordinary Netizens can improve it by adjusting the exposure compensation, which is usually "white plus black minus", that is, when shooting a large area of ??white, increase the exposure compensation appropriately.

Composition: A vast expanse of white is very beautiful, but the resulting picture may be too monotonous and not necessarily good-looking. You can add plants, architecture or humanities and other elements to the snowy scene to enrich the color of the picture. In addition, because the snow itself is white, it is easy to reflect light. It is difficult to reflect the layers and texture when the light is illuminated frontally or vertically. A dead white will also make the snow scene dull, so it is best to use side lighting, backlighting or side lighting. Backlight shooting; similar to portrait photography, the light is generally softer after sunrise or before sunset, so you can try to choose these two time periods for shooting.

4. What else should we pay attention to?

Anti-fall: In addition to the battery life and fogging issues mentioned above, the camera surface will become slippery due to the cold climate in winter. Especially those with metal casings, so be sure to attach a shoulder strap or wrist strap to the camera when using it, and do not hold it directly in your hand to take pictures.

Anti-static: Another danger for cameras in dry weather in winter is static electricity, so if you wear a lot of clothes that can easily produce static electricity, before taking the camera, it is best to touch the clothes that can act as The "ground wire" thing.

Keep yourself warm: If you take pictures outdoors for a long time in winter, you should protect your equipment and also pay attention to your own warmth. Try to wear light and warm clothes to facilitate activities. It is best to wear waterproof fabrics when shooting in snowy weather to prevent your clothes from getting soaked when the snow melts. Gloves are also suitable for photography that are easy to operate the buttons. Of course, hats and scarves are also not mentioned. They can also be used as cold protection covers for the camera when not wearing them.
