Comparison of an Aster (Michaelmas daisy) flower photographed in visible light (top), ultraviolet (middle), and infrared (bottom).
In visible light the flower head has a yellow centre with light purple petals. In ultraviolet light the centre of the flower is quite dark. In infrared the flower's appearance is not much different (in terms of tone) from in visible light. The stalk and foliage appear brighter in infrared.
