Black

Monochrome photography is photography where the image produced has a single hue, rather than recording the colours of the object that was photographed. It includes all forms of black and white photography, which produce images containing tones of grey ranging from black to white. Most modern black and white films, called panchromatic films, record the entire visible spectrum. Some films are orthochromatic, recording visible light wavelengths shorter than 590 nanometres.
