What are the parameters of the camera? How to set it?

Camera parameters are generally divided into EV, shutter speed, aperture and ISO.

EV value: the quantity reflecting the exposure degree. If the EV value increases or decreases, the shutter and aperture will be adjusted accordingly. The larger the EV value, the brighter the picture.

Shutter speed: represents the length of exposure time, usually in the case of sufficient light, the shorter the exposure time;

Aperture: a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens. Under the same ISO and shutter conditions, the larger the aperture, the brighter the picture will be.

ISO: sensitivity. The higher the sensitivity value, the more light is received. Under the same aperture and shutter conditions, the picture will be brighter with the increase of sensitivity. The noise (graininess) of the opposite picture will also increase.
