How does photographic lighting make shadows more natural?

Soft boxes are very useful, even if there is no overhead flash and flash. Therefore, it is suggested that when shooting, a group of lights should be covered with a soft cover, one on the left and one on the right, so that the products photographed will have more natural light and create local shadows purposefully. Mainly to reduce the later process.

If you don't add lights, you can also change the background after the cutout. The matting of PS can be done with a little skill.
