Regarding photography knowledge, prawns who are good at this aspect, please give me some advice. Thank you very much! !

The latitude of a photosensitive photo refers to the ability of the photosensitive material to correctly record the brightness range of the scene in proportion. The difference between the darkest part and the darkest part of the subject's surface can be expressed by the ratio between light and dark. Assume: the brightest part of the scene is 100 times brighter than the darkest part, then the ratio between them is 1:100, which is the difference between light and dark of the scene. The ability of a photosensitive film to accurately express the difference between light and dark in a photographed scene is the latitude of the photosensitive material, also commonly known as the exposure latitude.

Characteristics of studio continuous lighting: large size, assistants are often needed to help move the lights during shooting, and cannot be moved to the field for use (generators can be used for large shootings). These are all disadvantages. Then it can make models The subject has clear layers and a prominent three-dimensional effect, which makes up for the lack of three-dimensional effect in digital films and creates softer and more uniform light.
