The difference between pure black background and dead black in photography

The difference between pure black background and dead black in photography lies in light and details.

Photographic pure black background refers to the use of materials such as black background cloth or paper when shooting, which is made to appear pure black by light irradiation. In this context, the main outline is clear, the details are rich, and the overall effect is distinct. Dead black refers to adjusting the background to all black in post-processing. In this context, the outline of the subject is not clear enough, the details are few, and the overall effect is dim.

In practical application, the choice of pure black background and dead black depends on the shooting purpose and effect requirements.
