Photography under different lighting conditions

Photography is an art of perfect combination of light and shadow. If photography is compared to painting, then light is the pen used by photographers to paint, which can be used to shape objects, create atmosphere, add emotional appeal and express the author's feelings and thoughts. Let me introduce you to photography under different lighting conditions, hoping to help you!

1. Photography in different light conditions: What are the light changes and shooting methods in sunny days?

(1) Characteristics and expression methods of sunshine.

When the sun shines, the light comes from the front of the scene, which has the largest light receiving area and uniform light receiving. When taking photos along the light, because the projection of the subject is almost invisible, only a small part can be seen, so there is no contrast between light and shade, and the stereoscopic impression is poor; Also, because the subject and the background receive the same light, there is no obvious change in the brightness and tone of the far and near scenery, and the performance of the sense of spatial depth is also poor.

Advantages of smooth light:

The scene shot by 0 1. is evenly illuminated, and the exposure is relatively easy to grasp. By using the method of average photometry, the shot scene can get the correct sensitivity.

02. The scenery shot by Sunlighting is closest to its principle, which is more conducive to the expression of texture.

03. Using color film, the color reproduction is correct, the saturation is high, and the color is bright.

Because of the above characteristics, novices are the easiest to master exposure and are willing to use this light. From the perspective of professional photography, smooth light lacks expressiveness, and most of the films taken are two-dimensional planes, lacking three-dimensional sense. Therefore, professionals don't often use forward lighting, but mostly use side lighting or backlight.

In addition, when shooting people in Guang Shun, because the light source shines from the front of the subject, the subject is easily dazzled and uncomfortable. However, if the subject is a large scene that needs to use light evenly or does not need to pursue a three-dimensional sense or a sense of space depth, it also meets the performance needs, and it should and must be used, because whether it meets the characteristics of the subject and the needs of the performance scene is the only important basis for deciding what kind of light to use.

(2) Characteristics and expression methods of sidelight.

In sidelight, light comes from one side of the scene, so one side of the scene is illuminated and the other side is in shadow. According to the difference of light receiving area and shadow proportion, it can be subdivided into oblique side light and side light.

Under oblique light, the light receiving area of the shot scene is larger than the area of the shadow part, and the light comes from the left front side or the right front side of the shot scene, that is, the front light. The sharp contrast between light and shade makes the scene appear three-dimensional.

Side light, the light comes from the right, left or right of the subject, and the light receiving area and shadow area of the scene are almost the same. The whole scene is bright and dark, showing a strong sense of three-dimensional and three-dimensional space.

Side light is the most commonly used light in photography. Because the method of photography is to present a three-dimensional realistic spatial form on a two-dimensional plane, the pursuit of stereoscopic impression, that is, stereoscopic impression, is the pursuit goal of every photographer. There is no doubt that the three-dimensional picture is more expressive than the two-dimensional drawing, and it is also closer to the ideal of human pursuit of being close to reality.

Of course, sidelight also has its limitations. Because of the large contrast between light and shade, it is not conducive to expressing the texture of scenery details; When the contrast is too large, we should also use the method of supplementary light to make shadow lines appear on both sides of the shot scene, thus enhancing the performance of layering.

If you want to pursue the texture of the scene and the expression of the shadow of the details, you should not use side light. Side light is not as good as smooth light.

(C) the characteristics and performance methods of backlight

In addition, under the condition of low light irradiation angle, it can also be sensitive to the high density of scene background or the brightness of bright parts in painting, and can take a silhouette effect. When shooting a person's silhouette, the general figure appears in the form of profile to help express the outline. When shooting the sunrise and sunset, you can take the sky as the exposure basis, thus taking the characters into silhouette.

In a word, there is no fixed pattern in the use of lighting. We should choose the use of lighting according to the characteristics of the subject, the content of the performance, the lighting situation at the scene and the different modeling characteristics of each subject. For example, backlight can't express delicate texture. If we want to pursue the expression of texture, we should choose forward light and scattered light, and reverse light is not conducive to the restoration and expression of color.

(4) Characteristics and expression methods of top light

Top light comes from the top of the main body. For example, at noon, the sun shines on the top of the scene, and the prominent part of the scene will be projected into the concave place. The light is very strong, the light is very bright, and the contrast is blunt.

This light should only be used when it is necessary to show the outline of the subject. Generally, light should be avoided when shooting. So noon is not the best time for photography.

When you shoot people with the top light, there will be a heavy shadow under the eye socket, nose and chin, which will cause what people commonly call? Panda eye? Same dark circles. If overhead lights are needed, auxiliary lights should be used to eliminate or weaken shadows.

(5) The characteristics and expression methods in sunny days and shadows.

The light in the sunny shadow does not come directly from the sun, but from the sky and the environment. Therefore, in the shadow of a sunny day, the light received by each part of the scene is basically uniform, and the exposure will not change much from any angle. In addition, the shadow of the sun is soft, because it is scattered light, there is no obvious difference between light and shade.

Due to the above characteristics of light in the shadow of the sun, it is beneficial to express the details and delicate texture of the scene. Shooting people with this light can make their skin texture delicate, especially women and children, which can make their skin smooth and tender.

When shooting color film under the shadow of sunny day, because the composition of light is different from that of sunlight, there are too many blue and purple components, which are prone to color cast. Pay attention. It is also difficult to show a sense of three-dimensional space and depth when shooting in the shadow of the sun.
