The idea of a candid portrait is to capture people acting naturally. They should be unaware they are being photographed, as their behavior often changes once they become aware of the camera. We’ve all seen what happens when people are forced to smile for the camera, or to look at it while somebody is taking a snapshot. In one respect, candid photography is often regarded as being similar to environmental photography as both incorporate an “environment” in the photo, adding depth with a background that can help tell a story.

Candid portraiture is a form of informal portraiture, where the photo is relaxed, natural and sometimes accidental, not combining altered, effective lighting nor any “studio” conditions. However, this doesn’t have to mean unprofessional. Even if the subject is dressed in a formal manner, the end result can still be more casual. For example, a friendly, laid back businessman might wear his buttoned up suit for the portrait, but a natural, relaxed pose at his desk can make the portrait informal. All of the information collected by the artist about the subject will help determine which style is more appropriate.
