Portrait photography captures a person's expression, personality, and mood. It typically focuses on the face but may include the entire body and background context. Portrait images are seen in fashion, advertising, social media, art galleries, and photojournalism. The document discusses photographers Magda Berny, Yousuf Karsh, and Sylvie Bendel, noting how each brings out natural beauty or captures emotions in a raw, unedited style. It also contrasts old portrait photos, mainly in sepia or black and white, to modern color pictures that can be clearer and more natural.
