Spring crocus in UV light. Photograph of spring crocus (Crocus vernus) flower coloured to show areas that reflect (yellow) or absorb (dark areas) ultraviolet (UV) light. The UV pattern,known as a 'nectar guide',is thought to help attract pollinating insects,which can see in UV light. This image was taken on a digital camera adapted to filter and detect UV light. The resulting monochrome image was coloured on a computer. UV light is invisible to humans and does not have a true colour. See image B804/4381 for normal daylight version | |
