Which is better, a film director, a television director, a film producer, a literary director or a photographer? Practical? Good employment? Huge development space

I am a TV director, so I recommend taking this course, because the director is all-encompassing, and needs to touch various categories, such as production, camera shooting, post-production, special effects and so on. You mentioned it. It is a comprehensive knowledge, extensive and profound, and everything else is just a tool for directors. If possible, I recommend taking this course.
