A low key image contains predominantly dark tones. The histogram of a low key image will be shifted to the left-hand side.

Pro tip

When photographing low key images, remember to underexpose the camera by dialling the exposure compensation to between -1/3 and -3 stops, depending on the circumstances. If you don’t compensate, the black tones will come out grey instead of black.
