Infrared, or “IR” photography, offers photographers the opportunity to explore a new world – the world of the unseen. Why “unseen”? Because our eyes cannot see IR light, as it lies just beyond what is classified as the “visible” spectrum – that which human eyesight can detect. Mono infrared imagery is generally defined as captured at 720 nm or higher but may also be colour infrared images and post processing to monochrome.
Because everyday objects reflect infrared in proportions that differ sharply from that of visible light, the tonal relationships are wildly unexpected. Such near-infrared techniques used in photography give subjects an exotic, antique look. Green vegetation becomes white, whereas human skin becomes pale and ghostly. The resulting images look alien.
Some of my monochrome (and colour converted to monochrome) images can be seen below.
