People who know photography, how should glass bottles and porcelain bottles produce texture?

This problem is so complicated that the word 1000 can't be explained clearly.

To put it simply:

Q: Why is the edge of the bottle I photographed empty?

A: The aperture setting is too large, the shooting distance is too short and the lens focal length is too long. It depends on the actual shooting situation at that time.

Q: And it doesn't look textured?

A: Because photos are not transparent. It may be that the background color is too light, or the light is too strong or reflective.

Q: How should we ignite these materials?

A: No one answered. Different methods should be taken according to the shape of glass bottles to avoid light refraction and reflection. Photographers who have been playing for 20 years may not have accurate stolen pictures. However, using CPL is a good method.

Q: What kind of lamp do you use?

A: It doesn't matter. The key is the method of light distribution, that is, the illumination angle between light and objects. We should find the best position bit by bit.
