What is exposure compensation and how to adjust it?

Exposure compensation is an exposure control method. Exposure compensation is a shooting method that consciously changes the "appropriate" exposure parameters automatically calculated by the camera to make the photos brighter or darker. Photographers can adjust the brightness of photos according to their own ideas to create unique visual effects.

Adjustment of exposure compensation:

Generally speaking, the camera will change the aperture value or shutter speed to adjust the exposure value.

Cameras with exposure compensation can usually be adjusted by +2,+1, 0,-1, -2, etc. If the subject is underexposed, use positive compensation to increase the exposure, otherwise use negative compensation to reduce the exposure.

1. When the shooting environment is dark and the brightness needs to be increased, the flash can be compensated for exposure and the exposure can be increased appropriately.

2. When the photographed white object looks gray or not white enough in the photo, the exposure should be increased. Simply put, it is "the whiter the better", which seems to run counter to the basic principles and habits of exposure, but it is not. This is because the camera's photometry often focuses on the central subject, and the white subject will make the camera mistakenly think that the environment is very bright, thus underexposure, which is also a common problem that most beginners are prone to make.

3. When you shoot in front of a very bright background, such as in front of a sunny window, in front of a backlit landscape, etc. , increase exposure or use flash.

When you shoot people on the beach, in the snow, in sunny places or in front of a white background, you should increase the exposure and use the flash, otherwise the subject will be very dark.

5. When shooting the snow scene, the background light is strongly reflected by the snow, and the photometric deviation of the camera is particularly large. Increase the exposure at this time, or the snow will turn gray.

6. When shooting black objects, reduce the exposure to make black look purer in the photos.

7. When you shoot in front of a black background, you also need to reduce the exposure to avoid overexposure of the subject.

Extended data:

There are two reasons for using exposure compensation: first, the metering system of the camera sometimes has errors, and exposure compensation can correct the errors caused by active exposure; The second is to facilitate photographers to take pictures. Sometimes photographers want to darken or brighten deliberately, which requires compensation on the basis of active exposure.
