Is it necessary to learn photography if you like it?

First buy an entry-level SLR and feel for yourself to see if you really like professional photography that much. As for what to study in college and what to do in the future, most people have nothing to do with it. Even if there is, it is often only a few years ago. Learn what you want to learn and do what you want to do. This is the most ideal state. So it's important to find out whether you want to study or not.
