What are the photographic equipment? What is the knowledge of photographic equipment?

The latter kind of knowledge, the scope is too wide, and no one can make it clear just by one question. I can only answer the previous one briefly. The so-called photographic equipment mainly refers to the fuselage and lens. Of course, it also includes filters, flashlights (including other fill lights) and other accessories, as well as tripods and cables. These are commonly used, so-called photographic equipment and the like.
