As an actor starting out, the first thing you’ll be needing are headshots. Headshots are what you give to casting directors for an audition. These act as your résumé. Headshots are commonly an 8×10 professional photograph of you, taken from the shoulder up to your head. Then, you either attach or print your résumé at the back. So, make sure you have a whole supply of these as you prepare for casting calls and auditions.
