A useful technique for recording detail in objects, sites, and landscapes is to use film that is sensitive to the infrared spectrum so that it effectively responds to radiated heat rather than reflected light. Monochrome infrared film provides a wide range of grey tones. False colour infrared photography uses different colours to emphasize the contrast between features revealed through infrared photography. The colours bear no relation to the natural colours of the matter photographed.
