Low-Key Photography is a technique that emphasizes shadows and darkness to create a dramatic and moody atmosphere in the image. It typically involves using a relatively small amount of light, often just one key light source, to selectively illuminate the subject, leaving the rest of the scene cloaked in darkness. This technique can create a sense of mystery and intrigue, as well as highlight specific details or textures in the subject. Low-key lighting is commonly used in portrait, still life, and fine art photography to evoke emotions and add a touch of sophistication to the visuals.
