Headshots are required for all kinds of different purposes. For actors and stage performers, the use of a headshot in addition to their resume is a way to get their face in front of a casting director. Giving them a better position to be seen and given a screen test or reading, the headshot is an all-important part of any entertainer's portfolio.
For models, the use of their headshot is their vocation card and when talent scouts are on the lookout for a certain face they turn to the professionally reproduced photographs to give them the information that they need to screen candidates that are applying for modelling jobs throughout cities.

But it is not just a model and actor who find that they have a need for photographers to take their headshots. A number of people throughout the city seek out a portrait photographer to capture their essence in the headshots of political officials and professionals in a variety of careers.
For some people that are in the limelight, the need to update their headshots once a year keeps them ready for whatever lies ahead. Being featured in news stories, many people in the public eye are ready to present their headshots if they are asked to provide a photo to accompany an interview with the press.
