If you want to learn photography, do you have to learn P first?

Photographing is to shape the film, and later it is mainly to assist photography to beautify it. Personal suggestion: you can study the later stage (P picture) first, and then your aesthetics will be improved. The most important thing is that when you study photography, you will notice many problems in the later period, so that your films will be better and more exquisite. I hope my personal advice will help you!
