Achillea ptarmica 'The pearl' UV Vis IR comparison

Achillea ptarmica 'The pearl' UV Vis IR comparison
Comparison of Achillea ptarmica 'The pearl' flowers photographed in visible light (top), ultraviolet (middle), and infrared (bottom).

In visible light the flowers appear white with a pale yellow centre.

In ultraviolet light the flowers appear darker. The flowers were photographed when still covered with morning dew, the small water drops very noticeable in UV.

In infrared the flowers appear much the same as they do in visible light in terms of tone.
