Influence of exposure compensation on picture

What does exposure compensation mean?

1. exposure compensation is an exposure control method. If the shot picture is too bright or too dark, you can adjust the exposure compensation to achieve a "suitable" light and shade effect.

2. Exposure compensation is also an exposure control method, generally around 2-3EV. If the ambient light source is dark, you can increase the exposure value (such as+1EV, +2EV) to highlight the clarity of the picture.

3. Simply put, "exposure compensation" means that the photographer manually corrects the error caused by complex light in the camera automatic exposure system (increase or decrease, that is, positive and negative compensation) to ensure correct exposure. This correction process is called "exposure compensation".

4. EV (exposure compensation) is the exposure compensation for "adding a light" to a photo: it is a shooting method that consciously changes the "appropriate" exposure parameters automatically calculated by the camera to make the photo brighter or darker.

5. Exposure compensation is a method to adjust the exposure in full-automatic and semi-automatic exposure modes, because in some cases, the exposure given by the camera will be biased or fail to meet your requirements. At this time, exposure compensation must be used to adjust the exposure.

Will excessive adjustment of exposure compensation affect the image quality? Where is the specific performance?

Exposure compensation is an exposure control method. Generally around 2-3EV. If the ambient light source is dark, you can increase the exposure value (such as+1EV, +2EV) to highlight the clarity of the picture.

Oral English (very simple): exposure compensation refers to some occasions (such as backlight, night, environment with strong contrast between light and shade, etc. ), if you shoot normally, the photo will appear too bright or too dark. You should turn on the camera exposure compensation function and reduce or increase the exposure to make up for it.

One thing, for example, if you make more exposure compensation, the shutter will be slow; Similarly, if you shoot lower, the shutter will be faster.

In the exposure mode, the exposure compensation button can freely set the parameters of M-file, so the error caused by the camera's automatic metering can be corrected by adjusting the aperture, shutter and ISO. In P, S and A modes, the default exposure of the camera is normal, so exposure compensation is needed to correct it.

Camera interface parameters introduce three elements of exposure: aperture, shutter and sensitivity.

(3) Sensitivity: ISO sensitivity is the sensitivity to light. The higher the ISO value, the faster the response to light, but there is also noise.

There is no specific standard for the principle of black subtraction because of the different reflectivity of various scenes, so photographers should form the habit of carefully observing scenes, analyze the balance and reflectivity between black, white and gray, grasp the exposure essentials they need from thinking and practice, and shoot wonderful works.

Adding 0.3 to 0.7 can make the brightness of the scene more natural. (10) In some artistic photography, such as taking high-profile photos, it is necessary to increase exposure compensation to form photos with great contrast, so as to better express the author's shooting intention. Similarly, in some cases, if it is necessary to deliberately reduce the brightness of photos, the exposure compensation should also be reduced.

"Exposure Compensation", also known as EV (exposure value) adjustment, can be used to adjust the automatic exposure set by the camera up or down several levels. A value of 0 indicates the exposure recommended by the camera.
