“The photographer’s palette [is] a thousand shades of gray.” ~ H. E. Clark
Turning an image black and white, or monochrome as many call it, is a very subjective thing. Some images lend themselves to such a muted palette and some surprise you when they do. The absence of colour though is something we never actually experience in real life, even those who are coloured blind see some light colours. Yet when it comes to photography we accept it a presentation of reality when in fact it is hugely abstract.
