How to make a product stereoscopic?

You can try to illuminate with side light and oblique light, so that the projection direction of light forms a certain angle with the surface of the object. The object has both light-receiving surface, shadow surface and projection, and the color tone is rich, so that the object will have an obvious sense of pause. The positions of the lights on both sides are fixed, and the brightness of the lights can be changed by adjusting the power or distance of the lights. The three-dimensional sense is expressed by shadows. When the brightness of two lamps is different, the product will have a bright place and a dark place, and the dark side will produce a shadow. The ratio of different degrees of light and dark parts is called light ratio (light ratio can also be called contrast, which generally refers to the light reception ratio of dark parts and bright parts in the shooting scene, and is one of the important parameters of photography).
