I want to teach myself photography, I have no foundation, and I am not an art student. What textbooks can I use and what should I pay attention to?

Have an ordinary digital camera first, practice composition first, don't buy it without a SLR. Don't combine photography with SLR. Now the SLR is cheap, and there are a lot of pretending photos. It's really scary. These are the frontiers I gave you. You don't have to listen! Zero-based you and I recommend New York Institute of Photography, Photography is not difficult to learn. The former is very important! But you must practice shooting more.
