Often actors will ask me "what's your package?" or "how many looks do I get?". This is a reflection of how you want to market yourself, and it's the wrong approach. I believe the correct approach to marketing yourself and how many looks you need is to understand how others see you and make that align with how you see yourself. Be honest with yourself. You don't want a mismatch between what the casting director thinks you look like from your headshot and what you actually look when you come into the room. If you are a character actor you probably won't ever be playing Stanley Kowalksi and your headshot should reflect that to a degree. Each different "look" should be marketing a different side of you as a performer. So maybe you are an ingenue but you also have a hard rocker side to you. That's great if you are aware of it and can then take advantage of that. But don't go to a photographer and try and get as many looks as possible. It's a waste of your time, and personally I'm only interested in creating a single photo that markets you the best. My shoots involve a lot of talking beforehand about how you see yourself as a performer, how you think others perceive you, and your career history and goals because I want to hone in on exactly what makes you appealing to casting directors. If you don't know the answers to those questions, it's time to start thinking about them! Ask others, use a Johari Window (http://kevan.org/johari), talk to your agents!
