Low key refers to a photographic style where the image is dominated by dark tones and shadows, often with minimal highlights. This technique creates a dramatic, moody, or mysterious atmosphere and emphasizes shape, texture, and contrast rather than colour.
Understanding low key photography is important for portrait, fine art, and product photographers who want to convey emotion, depth, or a sense of drama. By controlling lighting and exposure, photographers can craft visually striking images that draw the viewer's attention to specific subjects or details within a predominantly dark composition.
