Watch: Most of the frame sinks into darkness, leaving one beam lighting half a face; the histogram in the lower right is pushed to the left. Dark, but with gradation still in the shadows.A line-art demo that only illustrates the technique, not finished footage.

Low-Key Lighting低调

Most of the image is dark, with a single beam of light revealing the key part. Mysterious, heavy, dramatic.

The technique comes first, followed by the subject, scene, details and aspect ratio. Paste it straight into an image model and swap in your own subject.

Low-key portrait, pure black background, a single key light from the upper left illuminating half the face of an old pianist and his hands resting on the keys, most of the rest sunk in shadow, the shadows still keeping the fine gradation of his wrinkles and the keys. 3:2, rich midtones between black and white.

Common pitfalls

Dark into dead black, nothing visible.
Lit too flat, neither dark nor dramatic enough.

Parameter tips

Spell out that the shadows keep detail; one key light, at most a little rim light.
