Hey! Welcome to the club!
I don’t have much formal film training, but I spent 20 years as a professional photographer, which helped me understand how to make things look beautiful.
First - BUY A CAMERA.
Second - TAKE A CLASS - my local spot is NW Film Center in Portland - I took ONE class and it helped me get enough basics to brush up my skills.
Third - MAKE FILM. Make music videos, short films, anything that gets your brain into the game. Eventually they’ll get good and you will have lots of ideas about making bigger things!
