Simply put, product photography is to put the real product or product model into the scene, while product modeling is purely based on computer-generated renderings, which can be carried out before there is no actual product or the actual product has not been made.

At present, photography and modeling drawings are widely used in product drawings. Simply put, if this thing can achieve the ideal effect through simple post-processing, then the cost, complexity and authenticity of shooting or modeling are far lower than the actual shooting. The most typical thing is the clothes with models. If this thing is difficult to achieve the ideal publicity effect through actual shooting, or the product photos need a lot of post-processing, then simply use the modeling map. The most typical are all kinds of metal products and glass products. The problem of reflection is obvious when shooting, and it is more troublesome to repair it later. Basically, it needs to be redrawn. Direct modeling is better, and the reflection part will be cleaner.
