When taking pictures, the camera may make extremely bright areas appear white (halation or blown out highlights), or extremely dark areas may become black and disappear from view (Black Crush).
The range in which the difference in brightness and darkness can be captured at the same time, from one step before halation (overexposure) to one step before blackout (completely dark, unable to see anything), is called the dynamic range. ) is measured.
The wider the dynamic range, the better the camera performance. However, no matter how powerful the camera is, it cannot match the ability of the human eye to capture images. For example, even if a scene is clearly visible to the human eye, when photographed with a camera, it may be overexposed or details may not be visible.
