what do i look like?
Taking pictures for press and publicity of actors, sports stars or public figures blends seamlessly into the realm of portraiture. After all, what is an actor's headshot if not a particular style of portrait, albeit with its own, more limited, conventions.
Generally it is thought that a headshot should not show too much 'character' in case that prejudices an agent or director against casting an actor in a particular role. That said, if the personality evident in the picture fitted the role perfectly, perhaps it would be an advantage!
In taking a more conventional portrait of an individual the context can play a significant part in portraying personality. Just as a headshot, taken against a plain backdrop without any distractions seeks to play down personality so an environmental portrait of someone in their own home, or place of work, can say so much more about them.
This form of portrait, much favoured in newspaper profile pieces, harks back to the tradition of painted portraiture. Such a commissioned photographic portrait would take pride of place on any wall.
