Please answer if you have a master. What's the difference between realistic painting and photos?

Realistic painting, although realistic, belongs to the category of painting. Painting expresses objects in a realistic way, but it is still an expression. Photography is the representation of objects. Performance can be combined with the author's subjective feelings, subjective emotions and so on, which is a very active creation. Although photography can also express the author's feelings, it is relatively passive in expression. After all, there is an essential difference between painting and photography, even if it is realistic, it is still painting.
