How to get started as an apprentice in wedding photography?

I've been studying photography for a year, and I don't know what to do or learn for a day. First of all, you should do what the assistant has to do, and see how the host lights the set, arranges the skirt, puts on the gauze skirt, fills the light with the reflector, and does all kinds of chores. Run faster, do things faster, and pay attention to details in the process of taking pictures. After that, the photographer will have a good impression on you and then communicate with the photographer. Learn the camera function, aperture shutter sensitivity, color temperature saturation, and the application of each lens. Look at the composition of the master's photos, the change of American lighting, and the photos taken from various angles and positions are completely different. There are still some pictures to see and learn more. Anyway, the road of photography should be taken step by step, and we must lay a solid foundation.
