Low-key photography is a genre of photography consisting of shooting dark-colored scenes, and emphasizing natural or artificial light only on specific areas in the frame. This photographic style is usually used to create a mysterious atmosphere, that only suggests various shapes, often graphic, letting the viewer experience the photograph through subjective interpretation and often implies painting objects or the human body with black non-toxic dyes or pigments. Edward Weston, Yousuf Karsh and Irving Penn are among the photographers experienced with the "black on black" technique.
