You should leave the photographer s studio with the film, drop it off at a good developer and ask for contact sheets. Again, if you don t have a manager or agent, ask someone knowledgeable of the industry or ask the photographer s opinion. There are different styles to choose from when picking a headshot, but they should always be in black and white. The most common headshots are shots showing your face and your upper body, and regular headshots where the focus in only on your face. Both are perfectly acceptable.
Commercial headshots are usually smiley and upbeat, showing a lot of personality and energy.
But again, portray your type. If you do not have commercial representation, you need to find an agent. A good way to do this is off a referral. If you do not have a referral, you need to mail your headshot and resume to as many commercial agencies as you can, requesting interviews. Keep in mind that agencies can receive hundreds of submissions a week, so yours can get lost in the shuffle.
