Photography accomplishment: exposure compensation!

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 raise or lower the automatic exposure set by the camera by several levels. A value of 0 indicates the exposure recommended by the camera.
