There are many things that need careful consideration when you go out to work on photography in the cold winter. In particular, you should pay attention to the effects of cold on photographers and on cameras and batteries.
First, photographers do a good job of keeping warm and cold
To create photography in a cold area, we must first pay attention to our own warmth. The photographer's clothing depends on the degree of cold. Generally, it is advisable to wear down jackets, electric socks and a thick sweater, and wearing a cap with ear caps on the head. Hands should wear silk or cotton cloth gloves, thickened duckweed fingerless gloves. Eiderdown gloves should be worn on the two cuffs of the backpack with a string so that they can be taken off at any time. Only silk gloves are used for shooting. Especially the nose, ears, fingers and other exposed parts of the most vulnerable to frostbite, we must pay special attention to protection, we must often rub, in order to speed up the blood circulation and enhance the ability to prevent cold.

Second, pay attention to moisture condensation
Generally, it is best to keep the digital video camera on the body during the winter. Let the digital video camera slowly adapt to the outdoor low temperature. If there is no good situation, it is better to put the digital video camera on the inside of the bag, and don’t rush out to the outdoors. , The average consumer will have a special digital camera package, the body heat will be passed to the inside of the package, so immediately take a digital video camera will make the lens and digital camera fog, and even the phenomenon of water droplets. The best thing here is to put the bag down and take out the digital video camera. This will be much better. At the same time, due to the cold weather, it is best to avoid shooting at low temperatures for a long time to prevent premature aging of the machine. In addition, when the digital video camera is taken from a cold place to a warm place, moisture condensation is likely to occur. At this time, because the camera band is adhered to the drum of the camera, the camera is automatically protected and the recording button temporarily becomes inoperative, so that it is impossible to continue shooting. So pay attention to avoid this situation. If you must take a digital video camera from a cold place to a warm place, such as when returning to the room from outside, you can first put the digital video camera in a plastic bag and seal it. When the air temperature in the bag reaches the ambient temperature When the temperature is removed, remove the plastic bag so that moisture condensation can be effectively prevented.
Once the lens is slightly fogged, remember to open the lens cover and remember not to hold the digital camera in the body, this will speed up the atomization. When you go down to the mountain, the digital video camera is put into the bag. Do not forget to take out the digital video camera within half an hour. The fog will be very serious. In the case of water vapor on the outside of the digital video camera and lens, do not open the lens cap, use a good point of paper towel to wipe the water vapor, and then wipe with a dedicated cloth to wipe the digital camera.
Third, the choice of reference and background
Snow is a must-see scene in the winter, but you must master the skill of shooting snow scenes. Otherwise, the pictures you shoot will not only be unattractive, but will also be dizzy. The snow-covered scenery may look a bit boring. You can add some colored objects to add to the snow highlights. For example, the use of ice poles or pine branches covered with thick snow, light poles dotted with colorful advertising signs, or buildings as the shooting foreground can increase the depth of space and improve the expressiveness of snow scenes. The connotation of the entire picture is more abundant, and it will not cause viewers to get bored with the daylight.
Snow is characterized by strong reflection and high brightness. If you simply shoot a white land, it will often make viewers feel dazzling and see nothing. Therefore, we should choose a darker background when shooting. This will make the snow scene. The contrast between the dark and bright scenery and the strong contrast between the dark and the dark make the whole picture richer. If you choose a background with high brightness, it will make the eyes of the viewer uncomfortable. The choice of shooting prospects is also very important. Due to the special nature of snow scenes, the use of branches, buildings, etc., covered with ice-cream or covered with thick snow as the shooting foreground, can increase the depth of space and improve the expressiveness of snow scenes. The connotation of the entire picture is more abundant, and it will not cause viewers to get bored with the daylight.
Fourth, select the filter and polarizer
When shooting in winter, it is sometimes necessary to pay attention to configure the appropriate filter. For example, in addition to the blue filter, other colors of the filter can absorb blue, purple short wave light, this can reduce the brightness of the snow, adjust the color, such as the use of neutral ash filter can reduce the brightness, you can The brightness of the scene is generally reduced to the brightness needed for exposure, making the images you take more natural and protecting the camera. Polarizer is also a kind of commonly used filter, which is often used in photography to eliminate or weaken the strong reflection of non-metallic surface, thereby eliminating or reducing the light spot. It can also be used to photograph the objects behind the glass, or the texture of objects that show strong reflections. In some special photography, the polarizer has a very important role. Adding a polarizer to the snow scene can absorb the polarized light reflected by the snow, reduce the brightness of the snow, and adjust the tone, while the polarizer does not affect the color of the original scene, making the entire screen layering and color saturation quite outstanding!
In fact, UV mirrors and polarizers belong to the category of filters. They are a good helper for shooting snow scenes. Although UV filters remove these ultraviolet rays, the blue-violet light waves transmitted to the photosensitive materials are reduced, clear vision, and enhance the contrast of far scenery. And color saturation, but because the digital video camera is sensitive to red light and infrared light and is not sensitive to violet light, adding a UV lens to a digital video camera will not achieve the desired filter effect, so the UV filter is The filter effect of snowscape shooting is not so necessary, but the protective effect of UV mirror is still worth mentioning. In the snow due to many uncertain factors may result in lens contamination, then with a UV mirror can be very good The protection of the lens, as long as you take a good wipe UV lens on it.
Fifth, white balance adjustment and backlight problems
Because the CCD sensor of the digital camera itself does not automatically adapt to the function, in order to approach the human visual standard, the digital camera must imitate the human brain and adjust the color according to the light, that is, it needs to adjust the white balance automatically or manually to achieve a satisfactory color. However, in the snow, the effects of the surrounding special environment often make the digital camera's automatic white balance function not very accurate, and the accuracy of the manual adjustment is better than the automatic adjustment, so it is better to use the manual function to adjust the digital camera at this time. The white balance, because only the white balance setting of the digital camera is accurate, the color can be restored correctly. Although snow scenes are white, but with the changes in time, surrounding scenery and other changes, white snow will also appear as different white, so when shooting different scenes of snow, you must pay attention to adjust the white balance of the digital camera at any time .
Six, equipment temperature considerations
Under the low temperature environment, the battery used by the electronic shutter camera is frozen, the power supply energy is often reduced, the battery capacity will be "shrink" a lot, probably only 2/3 of the summer, or even failure can not supply power, resulting in unable to take pictures. Digital cameras cannot work without power. Therefore, the first thing to pay attention to is the camera's power supply. It is necessary to prepare several sets of spare batteries. Keeping the spare battery in your pocket keeps it warm. Replace it with a cooler battery inside the camera. However, it is important to note that there are no other metal objects in the pocket to prevent the metal objects from bridging the contacts of the battery to cause a short circuit.
If you do not have a spare battery, you can remove the battery inside the camera and put it in your arms. When not taking photos, you can hide the camera in your clothes or wear a special camera coat to the camera to ensure that the battery you installed is at a proper temperature. When you need to take a photo, the camera can work normally.
Tripod
Photographic creation in the winter, tripods are also essential. Due to the weak light in winter, the use of the shutter speed can not be too high, not to mention the screen requires a longer depth of field, to reduce the aperture shooting, coupled with the use of filters and many other factors, but also to increase the exposure time. If you do not use a tripod, it is likely that the camera is unstable and blurring.
Plastic Wrap, cling film, shrink wrap, Saran wrap , cling wrap or Food Wrap is a thin plastic film typically used for sealing food items in containers to keep them fresh over a longer period of time. Plastic wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container without adhesive. The trend has been to produce thinner plastic wrap, particularly for household use (where very little stretch is needed), so now the majority of brands on shelves around the world are 8, 9 or 10 μm thick.
*Plastic Wrap With Cutterbox- A commercial grade plastic wrap ideal for use in restaurant kitchens, bakeries, and deli's. Rolls range in length from 1000 feet to 3000 feet. The plastic wrap with cutterbox rolls ranges in width from 12 inches to 24 inches. It provides an excellent cling and is comparable in quality to any food wrap offered on the market.
*Plastic Wrap With Slide Cutter- Same as the rolls in the cutterbox. The difference between the two is the slide cutter box is safer and easier to use. The slide cutter boxes are more expensive, but a better investment when safety and efficiency are important. Slide cutter box rolls range in width from 12 to 24 inches. All rolls that come with the slide cutter are 2000 feet in length.
The food plastic wrap with a slide cutter is designed for easy and efficient food packaging and storage. The slide cutter quickly attaches to the font of box. The concealed blade can easily be slid back and forth for fast film cutting. See the chart below for roll sizes and weights.
