Low key portraits use minimal lighting and shadows to accentuate the shape and contours of the subject. By keeping large areas of shadow, low key lighting can add depth and definition to muscles or abstract objects. Examples show a model displaying emotional pain with shadow covering most of his face from backlighting. Another confident model is lit from above, leaving shadow in the top corners. A portrait of Tupac uses a hooded shadow across his serious, emotionless eyes and illuminated face to draw attention to the gun he holds, portraying him as a troubled man.
