Get a camera and start filming on your own. Take what you’ve learned from school and apply it to your outside work. Take what you like and what resonated with you. Learn to ignore what you don’t like.
The reason that filming outside of an institution will help you is because at school you will often be told there is a best way to shoot something. And in an academic sense, there is. But you should remember that you are an individual, and a storyteller. Your voice is through the lens of your camera and you should learn to speak it.
