How to show the night scene effect?

For example, shooting the train station during the day, the picture is not lively, there are not many trains, and the atmosphere is not strong. If you shoot at night, you can use the method of multiple exposures to open the shutter every time the train comes, so that bright locomotive lights can stay on the picture, thus obtaining the busy effect of train operation.

There are many light sources, and double-night photography often has multiple light sources at the same time, which is different from daytime photography. Such as lights, flames, moonlight or the afterglow of sunset. It plays a dual role in night photography: it is not only the light source of illumination, but also an indispensable part of the picture. If there is no light, fire or moonlight in night photography, the atmosphere of night photography will be greatly weakened.

4 subject, still life is the main way to shoot night scenes, and the subject is mainly static scenery, which is generally not suitable for shooting fast-moving objects. Due to the weak light at night, the illumination of various scenes is very low, and it takes a long exposure time when shooting. In addition, the contrast of night light is very strong, and there is a great difference between bright and dark places. If rapid exposure is used, the negative film is underexposed, the picture level is reduced, and the photo lacks charm.

Second, the matters needing attention in night photography

1 Prevent the camera from moving. When shooting at night, the camera should be screwed on a tripod or placed in a stable and firm place. Adjust the aperture, press the shutter and observe the scenery. Don't touch the fuselage, especially when exposed many times. Otherwise, the negative film will appear ghosting, which will lead to shooting failure.

2 The use of aperture When shooting night scenes, special attention should be paid to the use of aperture. Because it affects the clarity of the scene. Some night scenes, because the light is very dark, can not accurately determine the shooting distance. Therefore, the methods of reducing aperture and increasing depth of field are often used to deal with it. When shooting night scenes, the commonly used aperture is f5.6 or f8. The positions of some scenes are relatively fixed, and the light changes little. The aperture can be appropriately smaller, but the exposure time should be extended accordingly, so that the clear range of the scene can be larger. When multiple exposures are made, the exposure can be adjusted through the aperture according to the intensity of light on the spot.

3 Measurement of distance The measurement of shooting distance should be as accurate as possible, otherwise it will directly affect the clarity of the scene. Generally speaking, when shooting a big scene at night, the distance can be placed at infinity. If you take a shot or close-up, you should focus on it. The clearer the focus, the better. The focus should be fixed on the position of the subject or the main part of the scene, and then measured after being illuminated by a flashlight. You can also use bright spots near the subject instead of measurement. Once the distance is determined, it cannot be changed at will during shooting.

4 mastering the exposure of night photography is more complicated, and you can't rely on the exposure meter. We should explore the law from reality. There are two exposure methods: one exposure and multiple exposures.

(1) One exposure: One exposure is easier to master. Before shooting, before shooting, put the camera on a tripod, and then determine the shooting object and framing range. After framing, check the fixation of the camera again, and control the opening of the shutter with the release of the cable to make a timed exposure. Without cable release, the lens cover can be used to control the open shutter.

(2) Multiple exposures: More than two exposures are called multiple exposures. It is a method used only when one exposure cannot complete the shooting task. Using multiple exposures, some scenes can be shot in stages, making the picture rich in content and lively in form.

When using multiple exposures, we should pay attention to: first, separate the scenes with different light intensities, so that the darkest scene is exposed more first, and the brightest scene is exposed less later. Second, some scenes can't be exposed first or more, and artificial light can be used to properly enhance the brightness of dark scenes to adjust the contrast of the picture. Thirdly, for some scenes with too strong or too weak light, the film can be thinned or thickened, and enlarged can also be remedied if it cannot be adjusted on site.
