Photography is a mainstream art form today, with many categories. In general, it can be divided into commercial photography and artistic photography. "Deep Light Vision" categorizes its photography business into two types: one is product photography, and the other is commercial photography. Product photography is easy to understand—it involves photographing various products, from large items like cars and clothing, to small ones like watches and perfumes, covering all aspects of what people come into contact with. However, what is commercial photography? It is generally believed that any act of providing photographic works in exchange for corresponding remuneration falls under commercial photography. Using this definition, product photography is also considered a commercial photography activity. Nevertheless, we have reinterpreted "commercial photography." It refers to supplementary photography activities carried out to support product marketing and brand promotion. This includes: executive photography, business scene photography, employee image photography, workshop photography, LOGO mark photography, production activity photography... These types of photographs allow the public to gain an indirect understanding of a company's essence, build consumer confidence, and serve functions that product photography cannot achieve. Actually, this concept was from three months ago. Now, we might as well refer to commercial photography mentioned in this article as advertising photography. During the next website redesign of Shenzhen Photography, we will make these changes accordingly.
