Monochrome
Monochrome denotes one colour and in art and film photography traditionally refers to black and white. In the use of ink for drawings, monochrome can also refer to combinations containing only tones of a single colour, such as blue or shades of brown. Monochrome can also refer to sepia where works can be made up from a number of tones of a specific colour depending on the the intensity (dark) and lucidity (light) in the image. In early photography monochromatic images were produced by methods such as ambrotype and daguerreotype.
