One easy way to learn is to watch movies, watch the director’s commentary version of them, read film scripts and compare to what you see on the screen, watch breakdown lectures with directors, cinematographers (camera department), or wardrobe, or anything you can learn about. It will help a ton give you an understanding on how a film set works.
Also if you know someone who works professionally in film set it can be helpful, since you can throw questions their way about anything you’re curious about. A lot of film sets offer internship so you can sign up for that where you can work as a PA and learn a ton by seeing everything happening in person.
