Why is the makeup artist's salary lower than that of the photographer, and the makeup artist is also very hard, and he is also a tour guide, equivalent to a photography assistant, but there is no photographer? If photography is the main place, the photographer's salary will of course be higher and the photographer's level will be higher. Makeup artists are an auxiliary photographer's profession. If you are a makeup artist and photographer who makes movies, for example, the salary is basically the same, so there is a difference between powder and powder.
