What’s Dynamic Range?

When taking pictures by the camera, there are some cases which the part is too bright (halation / overexposed), and the part is too dark (blackened).

Dynamic range is called the range of contrast difference (defense range) which can be concealed at the same time to the edge before the halation (white jump) from black collapse (too dark to nothing). The unit is db (decibel).

The larger dynamic range number, the better camera.

However, when comparing human eyes and cameras, naked eyes are superior even with excellent cameras.

For example, even if you can see it with naked eyes, shooting with a camera may cause halation (white overexposure) or may not be visible.
