The term Monochrome comes from the Ancient Greek work monochromos (mono: single; chromos: color), meaning having one color. A monochromatic image reflects colors in shades of limited colors or hues. Images using only shades of grey are called grayscale or black-and-white (BnW).
Monochrome photography means exactly just one color i.e an image shows different amounts of light of a single tone, but not a different hue. It includes all forms of black-and-white photography, producing images containing tones of neutral grey ranging from perfect black to snow white. Monochromatic photography is a great technique to detach individual colors and make them stand out.
There’s not much difference between grayscale and monochrome photography or images, the term monochrome is usually used when tones of only a single color such as green-and-white or green-and-red, are used. Whereas, the term grayscale is used when tones of primarily black-and-white, are used.
