>>4217503>What do I learn Photography History. By getting an overview of the rather short history of the medium, you will find ways of working that appeal to you and that you can imitate. You let yourself drift immanently and thus learn not only different approaches to photography, but in imitation also the technical apparatus of the camera.
Over time, the various influences and your other interests and preferences mix to form your own style. Try to avoid Youtube, /p/ and other places. Here you only learn technical aspects at an extremely high time cost.
As an advanced photographer, project-based work is highly recommended. A cohesive project provides motivation and direction. A project gives you purposeful work and tangible results instead of just taking snapshots with expensive equipment. A project provides you with a goal.
what do I buy?
Photobooks. Start with the history of photography – not theoretical, but a book with as many important photographers as possible.
Don't fall into the gear rabbit hole. It never ends.
