A popular photographic concept on
Instagram, involving all shots and images in a purely
monochromatic theme, using a black-and-white tone (hence the "mono", from "monochrome") to add contrast,
perspective, and/r create an entirely new abstract concept to the capture. However, it isn't simply a "black-and-white" shot. It is intended to be used for greater artistic effect. Invented by a guy named Josh, from Singapore.
