What is los in photography?

In photography, it is generally called ISO, not IOS.

ISO is the code of sensitivity in photography. The larger the number after ISO, the higher the sensitivity and the better the exposure of photos in weak light.

Generally speaking, ISO value, aperture value and exposure time are several important values in a good photo. Generally, when shooting, the balance is adjusted according to different light and moving speed of the object. White balance is to adjust the color of photos.

ISO can generally be purchased from ISO64-20000.

Of course, the better the camera, the wider the range of this value.
