Monochromatic or monochrome are terms usually used in photography to describe an image produced with a single hue or tone, rather than the usual colour photography. Monochromatic photography is considered more subtle and leaves room for interpretation, it is often considered more moody. Monochrome images are usually not direct renditions of their subjects, but are more likely to be abstractions from reality, representing colours in different shades of grey. In the photographic world the term monochrome usually means black and white but it may also be used to refer to other combinations, containing tones of a single color, such as blue and white or yellow and black. It may also refer to the widely known toning called Sepia which contains tones from light tan to dark brown.
