A good Celebrity photographer can catch the lighting just right to show off the physical look of the person, and is capable of pulling it off even when the subject is in motion. Even more important, in my opinion, is catching the glimpse of emotion within the individual. The sparkle in the eye, the twitch at the corner of the lips, the stance or body language captured all help the audience get a sense of what the celebrity is feeling. Photographers who work with people know how important it is to catch those moments.
Celebrity photographers can work for newspapers, magazines, modeling and talent agencies, private individuals or even for themselves, as freelancers.
