A digital photo portrait of mother and child

Unlike many other photography styles, the subjects of portrait photography are often non-professional models. Family portraits commemorating special occasions, such as graduations or weddings, may be professionally produced or may be vernacular and are most often intended for private viewing rather than for public exhibition.

However, many portraits are created for public display ranging from fine art portraiture, to commercial portraiture such as might be used to illustrate a company's annual report, to promotional portraiture such a might be found on a book jacket showing the author of the book.
