What problems should I pay attention to when going out for photography?

There are many things that need to be seriously considered when going out for photography creation in the cold winter, especially the influence of cold on the photographer himself and the camera, battery and film.

When creating photography in cold areas, we should first pay attention to our own warmth. The photographer's clothing depends on the degree of cold. Generally, you should wear duck down clothes, electric socks and a thick sweater, and wear a duck down hat with earmuffs on your head. Hands should wear gloves made of silk or cotton cloth and fingerless gloves with duck down pad. Duck down gloves should be tied to the two cuffs of the backpack with ropes so that they can be taken off at any time. Only wear silk gloves to shoot. Especially the exposed parts such as the nose tip, ears and fingers are the most vulnerable to frostbite, so special attention should be paid to protection and frequent rubbing to speed up blood circulation and enhance cold-proof ability.

In a cold climate, it is necessary to avoid the camera experiencing excessive and rapid temperature changes. When the camera is suddenly exposed to the cold from indoor to outdoor, the moisture in the hot air in the body will frost or freeze immediately, the metal shutter is easy to fail, and the lens is easy to crack, which brings unexpected trouble to photography creation. In this case, photographers should take effective measures in advance to prevent it. When not taking pictures, take the camera with you, hold it in your arms, and take it out when necessary. When you enter the room from the outside, because there is heating in the room, the hot air will condense on the lens, view frame and film, which will cause the metal parts to rust and fail. Don't take out your camera immediately after returning from the outdoor to the indoor. Only when the temperature is close to the indoor temperature can it be taken out, so as not to cause the components of the camera to fail.

When shooting or shooting, be careful not to let the frozen metal part directly contact the facial skin, and also be careful not to breathe into the camera. The moisture produced by breathing will frostbite or stick to the skin, and may also make the viewfinder or lens on the camera wet, forming a thin layer of ice, which will affect shooting.

Special attention should be paid to protecting the film when creating photography in winter. Because in the cold outdoors, the film will become brittle due to the cold. It is easy to crack, break or suddenly tear, and the rolling hole on the film often becomes the starting point of cracking. So when installing the camera, it is best to do it indoors. If you need to roll up outdoors, take the film with you in advance and put it in your pocket to warm up. When changing to film, you can take it out and put it in the lee and pack it as soon as possible. Be especially careful when shooting. No matter whether you move the aperture or the shutter, you should not move too fast or use too much force to avoid damaging the parts or breaking the film. In the cold winter, the climate is relatively dry, and the film and camera are prone to generate static electricity, which will cause indelible curve marks on the film. This phenomenon usually occurs when entering and leaving the coil. The best way to overcome this phenomenon is to move gently, slowly and step by step when entering and leaving the coil, without sudden exertion. Films taken in winter, especially color films, should be developed as soon as possible, because the density will decrease if they are left for a long time, just like underexposure.

In the low temperature environment, the battery used in the electronic shutter camera often freezes, so the power supply energy is often reduced or even unable to supply power, which makes it impossible to take pictures. When going out to take pictures, the photographer needs another battery to replace the cold battery in the camera. If there is no spare battery, he can take it out of the camera and put it in his arms to keep warm, and then install it again. When you don't take pictures, you can hide the camera in your clothes, keep the installed battery at a suitable temperature by body temperature, and only take out the camera when you need to take pictures.

Winter photography is very different from spring, summer and autumn. In winter, the light is soft and the illumination is low, so it is necessary to prevent underexposure. Under normal circumstances, the exposure in winter is one level higher than that in spring and autumn, two levels higher than that in summer, or the shutter speed is reduced by one or two levels. When shooting snow scenes, it is necessary to prevent underexposure.

In winter, the weather is cold, and the light time suitable for shooting is short, only four or five hours. For landscape photography, it is necessary not only to be cold outside but also to be hot inside, so as not to miss the precious time of taking pictures. Especially in cold weather, the electronic and mechanical parts of the camera will fail because of the low temperature, resulting in the shutter can not be opened, only to see the wonderful scenery, can not shoot. So when you go out to shoot in winter, you should put the camera in your coat or cotton-padded clothes in advance, and don't take it out until shooting. Be quick when shooting, take it out of your clothes quickly, be extra careful when operating, slow down, and put it back in your clothes immediately after shooting.

In order to highlight the effect of heavy snow, the shutter speed of photography should be below 1/60 seconds, and dark scenes should be selected as the background to clearly show the traces of white snowflakes and snowflakes flying. It is also necessary to put the camera under an umbrella or in a sheltered place to prevent snowflakes from falling on the lens and affecting the photographic effect. In case of falling snow, you should immediately wipe it off gently with absorbent cotton or lens paper, or remove it with an air brush, but you can't blow it with your mouth, because the hot air blown out of your mouth will make the snow dissolve quickly and form frost and stick to the lens, which is difficult to remove in a cold environment.

Filters are essential for shooting snow scenes in winter, especially for color photos. The white snow under the blue sky reflects a lot of purple-blue light, which will have a great impact on the film, making the color film seriously blue, and the white snow almost becomes Lan Xue. Practice has proved that it is better to add a Leiden 8 1B or Leiden 8 1A filter in front of the camera, which can prevent the over-cooled blues from appearing on the color film and improve the color. When taking black and white photos, you need to add the No.2 yellow filter or green filter in front of the camera, which can improve the contrast, especially the contrast between snow and shadows. If you add a polarizer, you can eliminate the reflection of some scenery on the ice and snow.

Tripod is also essential for winter photography. Because of the weak light in winter, the shutter speed should not be too high. And sometimes the picture needs a long depth of field and needs to narrow the aperture to shoot. In addition, there are many factors such as the use of filters, and the exposure time should be increased. If you don't use a tripod, it is likely that the camera will be unstable and the picture will be blurred.
