As in every profession, there is also some rules and ideas that can help you to improve your photography skills. Although, it does not mean that one has to follow these rules by any means. In fact, sometimes you create something extraordinary, magnificent, and stunning by breaking these rules. However, in order to break them, you need to know them first. Here are the books that may help you to get some ideas about photography and cinematography rules:
These books are good to start and will lie some solid background for your photography skills. Most of them are also available for kindle, which I would not actually recommend since kindle can show you only black and white while color is an important matter of this topic. Moreover, if you do not want to stop in photography but develop further and try your skills in filmmaking, then you may need to read as well
There are also many interesting YouTube tutorials that you can find online. A channel in YouTube that I would recommend is Filmmaker IQ. The most important thing in my opinion is not to jump from one to another but to finish something that you have started. If you also have any books to recommend, please feel free to note it in comments below.
