Not those who don't know photography.

Recommended] the book "Image Restoration and retouching" by ]katrin eismann wayne paimer (because I have only read this book, I don't know the rest).

In addition, watch Wang Zhi and Lu Yu's talk show and Deng Wei's interview. Photography is closely related to life and can also be used as a hobby, but you must have your own understanding of life, otherwise you can't express it to anyone. ...

This is my superficial and one-sided view. I can't use a SLR camera, but I like it. I hope I have a camera myself one day. ...
