Infrared refers to the rays of light that lie beyond the red end of the visible electromagnetic spectrum and are invisible to the human eye. In photography, infrared light can be captured using specially sensitized film or digital sensors with infrared filters, producing unique black-and-white or colour images with distinctive tonal effects.
Infrared photography is valued for its ability to render foliage bright white, darken skies, and reveal details not visible in normal light. Understanding infrared light allows photographers to explore creative effects, capture hidden textures, and experiment with alternative photographic styles that stand out from standard visible-light images.
