What if the background photo is exposed at night?

If the brightness of the light is too high, just adjust the light power and reduce the brightness to a suitable level. If it's not light, you have to adjust the exposure parameters of the shooting equipment. The camera can be adjusted manually, and the mobile phone usually exposes itself automatically.

Exposure refers to the process of putting the photosensitive plate on the workbench of the printing machine, putting away the negative film and obtaining the potential or visible image through exposure. Exposure is the basic process and main feature of all photochemical imaging methods. Exposure, that is, the computer uses natural light source mode, which is usually divided into manual exposure and automatic exposure. The quality of the photo is related to the exposure, that is to say, how much light passes through the photosensitive element to get a clear image. Exposure is determined by light passing time (shutter speed) and light passing area (aperture size).

Using special light can often produce many different effects. Let's take a look at some principles of exposure: 1 ensure that the brightness of two subjects is the same, thus correctly showing their color relationship. The change of light and shade is a good place to enhance the artistry of the picture, which can make the color of the picture look more gorgeous. Directional light can improve the texture of the picture very well. Exposure is a comprehensive problem, not simply measuring the brightness of a person's face with an exposure meter. When shooting portraits in outdoor wedding photography, we should first consider the exposure of the environment, and then unify the brightness of the characters and the environment through some methods or intentionally strengthen the differences.
