An artist’s portfolio is an edited collection of their best artwork intended to showcase an artist’s style or method of work. A portfolio is used by artists to show employers their versatility by showing different samples of current work. Typically, the work reflects an artist’s best work or a depth in one specific area of work.
A photography portfolio can focus on a single subject. It can be a collection of photographs taken with a certain type of camera, in one geographic area, of one person or a group of people, only black & white or sepia photos, a special event, etc.
