False colour film is a type of photographic film that renders colours differently from how the human eye perceives them. Instead of capturing natural hues, it produces images in which certain colours are exaggerated, shifted, or replaced, creating striking and often surreal effects. A common example is Ektachrome Infrared film, which records infrared light and renders foliage, skies, and other elements in unusual tones that do not match reality.
False colour film is particularly useful in scientific, aerial, and artistic photography. In scientific applications, it can reveal details invisible in normal light, such as plant health or geological features, while in creative photography, it allows photographers to produce visually compelling and imaginative images. Understanding how to use false colour film enables photographers to explore both technical analysis and artistic expression in ways that ordinary colour film cannot achieve.
