Recently, photography has become almost as widely practiced an amusement as sex and dancing - which means
that, like every mass art form, photography is not practiced by most people as an art. It is merely a social
rite, a defense against anxiety, and a tool of power.
-Susan Sontag, On photography
Photography is a form of nonverbal communication. At its best, a photograph conveys a thought from one person, the
photographer, to another, the viewer. In this respect, photography is similar to other forms of artistic, nonverbal
communication such as painting, sculpture, and music.
-Bruce Barnbaum, The Art of Photography
