I want to learn photography, but I have no foundation. I just patted my cell phone.

Photography is not difficult to learn. If you want to be a photographer, you need to master art, color, composition, spatial logic, photography foundation and so on. It needs long-term accumulation and precipitation. Beginners can find some related photography teaching materials first, and buy a camera to learn if possible. After understanding, I will choose the training direction according to my own needs. And if you are confused, find a teacher to see how to choose and develop.
