Who gives some advice on how to shoot backlit landscape works ~ ~ the selection of metering points and other applications ~

Backlight comes from the back of the scene, and the subject we shoot is often a dark part without direct light, which is not easy to show the light and dark levels and lines of the scene, with large contrast and many changes. Without rich shooting skills and experience, the exposure of the subject will be inaccurate and the unique charm of backlight photography will not be displayed. Therefore, photographers should be able to skillfully use and master the following skills when shooting backlit photographs.

When shooting with 1. backlight, use the central key to measure light, and at the same time increase the exposure compensation of 1/3-2/3EV, which can ensure that the subject is fully exposed. If the light contrast is large, you can also turn on the flash to fill the light. Exposure should focus on the exposure of the main body, and the rest should be ignored. If you shoot the sunrise or sunset, you should take the exposure value of the sky or the sun as the main basis.

2. When shooting flowers, plants, people, animals and other scenes with clear outline and transparent texture, we should choose a darker background as the contrast, and use high light as the photometric basis when exposing, so as to create a strong light ratio contrast, strengthen the backlight effect, and achieve the artistic effect of clear outline and prominent subject.

3. When shooting the silhouette effect, the exposure should be based on the bright background brightness.

4. Because the camera is facing the strong light source when shooting in backlight, we should pay attention to the influence of glare. Try using a hood or using hands, hats, cardboard, etc. Stand in front of the camera or adjust the shooting angle to prevent glare. There are two most commonly used backlight shooting effects: one is silhouette effect, and the other is "side light" effect. The following are backlight photos taken at the same time, place and subject matter in different ways, with completely different effects.

Silhouette effect

The shooting of silhouette effect is relatively simple, and the light exposure is taken as the standard when shooting, mainly to reflect the unique tone and atmosphere of the environment, as shown in the above picture.

The background is simple and there are ways.

Landscape photography not only emphasizes the choice and arrangement of the subject, but also can't ignore the treatment of the background. Background refers to the scenery behind the subject to set off the subject, so as to emphasize the environment in which the subject is located. Background plays an important role in highlighting the image and enriching the subject connotation. Background processing is an important link in the structure of photographic pictures. Only by careful selection in shooting can the picture content be refined and accurate, and the visual image be perfectly expressed. The ideal background should be simple and pure, with exquisite visual elements and harmonious colors. Experienced photographers are good at mobilizing various skills to realize the simplicity of the background, and all unnecessary elements in the background that hinder the main body from protruding should be subtracted. To sum up, there are several ways to improve the background:

The first is the fuzzy method.

That is, a larger lens aperture (such as F2 or F2.8) is used to reduce the depth of field as much as possible, and the focus falls on the subject, so that the background behind the clear subject is blurred, thus achieving a good effect of setting the virtual against the real.

The second is the occlusion method.

That is, using rising clouds, misty white fog, branches and leaves of trees, or sunny surfaces of mountains, walls and other objects to hide the background, thus highlighting the main body.

The third is the avoidance method.

That is, adjust the shooting height, or lean back to avoid the messy scenery on the horizon, and set off the main object neatly on the sky background; Or take the road, water and grassland as the background, so that the outline of the main body is clear and a concise background is obtained. Sometimes a long focal length lens is used to reduce the background, and messy scenes are excluded from the picture.

High-profile shooting of scenery

High-profile, also known as bright tone. Usually, light-colored photos are called high-profile photos. The tone of high-profile photos is mostly light, which consists of several levels from light gray to white. Generally concise and clear, suitable for expressing the theme with white as the keynote. Although high-profile photos are dominated by high-grade light tones, they still require rich levels and do not exclude small dark tones. Due to the large area of light tones, a small number of deep tones are more prominent, which can play the role of finishing touch.

When taking high-profile landscape photos, we should pay attention to five points: first, choose light-colored scenery, and the colors of the subject and companion should be as close as possible; Second, choose a light background, and use a white or light gray background to set off the dark subject. These light backgrounds can be rain, fog, clouds and smoke, or endless mountains and vast waters. Thirdly, the front light or diffused light is used to obtain a soft and flat image. In sunny days, a shadowless lamp image can be obtained by using flat and direct front light; In rainy days, images with soft contrast can be obtained by using symmetrical and peaceful diffuse light or reflected light; Fourth, increase the exposure, according to the specific situation, increase the exposure by 0.5 ~ 1.5 on the basis of the normal luminosity value, which can brighten the background; Fifth, the light ratio should be controlled within 1∶2. If the light ratio is too large, the highlights will either be completely lost or the gray tone will darken, thus losing the characteristics of high-profile photos.

In natural scenery photography, high-profile techniques are often used to express delicate, ethereal and vast beautiful scenery. There are many natural backgrounds that can be used. For example, when shooting Jiangnan scenery, it is often based on the concept of blank to highlight the main scenery, with simple composition and close technique, and the rest gradually change into hazy distant trees, fresh water, fog, rain and smoke. There is also shooting snow scenes. Almost pure white snow is an excellent background for seeking high-profile images. In architectural landscape photography, the method of selecting a corner and a half of the scene or focusing on one side is often used to attract the attention of the viewer to the empty space, giving people a space for meditation and reverie. Also, with the sky as the background, elevation shooting is adopted, and the exposure is subject to the luminosity value of the subject. The sky is pure white due to overexposure, which can well show the high-profile effect of the whole picture.

Low-key shooting scenery

Low key, also known as dark tone. Usually, photos with strong colors are called low-key photos. The tones in low-key photos are mostly black and dark gray, which are composed of several levels from dark gray to black. The tone of the whole picture is heavy and deep. Generally, it is suitable to express the theme with dark black as the keynote, to create a solemn, dignified and quiet atmosphere, and to reflect the characteristics of vicissitudes and calmness. Although most low-key photos are dark shadows, small areas of white highlights are not excluded. Due to the large area of dark tones, small pieces of white are particularly obvious, forming a visual center, making the whole picture vivid.

When shooting low-key landscape photos, we should pay attention to six points: first, choose a scene with deep color, and the color of the partner should be relatively deep, which is in harmony with the low-key of the subject; Second, choose a dark background, pure black or dark background can set off the light-colored subject; Thirdly, using side light or side backlight, these light levels, viewed from the direction of the lens, have a small light receiving area of the main body, which is profile light and easy to obtain dark light images; Fourthly, to reduce the exposure, we should reduce the exposure by 0.5 ~ 1.5 on the basis of the normal photometric value according to the specific situation, so as to darken the background; Fifth, the light ratio is large, which can be greater than 1: 4 or even1:8; Sixth, using the shadow of the sun as a foil is to use the shadows such as mountains and walls that the sun can't shine as the background to hide the messy lines in the shadows.
