Are the functions of "exposure compensation" and "brightness" the same?

"Exposure compensation" and "brightness" are not the same thing at all;

1, the brightness is for the display device, the display has a brightness level, and the LCD screen of the camera has a brightness level, but there is no brightness level when the camera takes pictures.

2. Exposure compensation is only available for cameras with automatic exposure, but not for cameras without automatic exposure (metering) in the early days. You can look at the cameras before 1950s. Neither Leica nor Zhuoerji has the right to control the exposure compensation, or even this statement.

Briefly talk about exposure compensation:

In an automatic exposure camera, the photometric element measures the ambient light to obtain the EV value, and automatically adjusts the aperture and shutter size according to certain rules. People who use cameras can't interfere with these jobs. In order to intervene in this work, three kinds of manual intervention operations are designed (mainly):

First, aperture optimization (also called priority)

B, shutter optimization (priority)

For the above two operations, under certain circumstances, the photographer needs a large depth of field, and the camera is not assigned to me. I will step in, choose a small aperture first, and the shutter will be assigned to me by the camera. This is called aperture optimization. Conversely, the same is true for shutter selection. I am shooting sports. First, I choose the shutter, and the camera will automatically set the aperture for me.

C, and exposure compensation are the same concept: whether it is automatic, aperture optimization or shutter optimization, it is based on the results of photometry: the values of aperture and shutter are calculated according to the requirements of EV value, but according to the photographer's experience, the measured EV value is not good, so we intervened artificially. You measured EV= 14, such as backlight. I think it's EV = 65438+.

In the past, for cameras without metering, we used to say "add half an aperture" and "subtract one aperture". In automatic exposure cameras, only exposure compensation can be used.

In addition, when using aperture optimization or shutter optimization, exposure compensation can still be performed without sacrificing speed and so on.

I don't know if this is clear.

Supplement:

Seeing your supplement, I would like to ask, what model is your camera? So I can analyze the real significance of changing the camera model to this setting.

Yes, a camera is a mobile phone with a camera? This is because its CCD is not good and it has additional functions. I can tell you that no digital camera has this function. So I was surprised.
