Ultra Violet Imaging

As humans the electromagnetic spectrum available to us ranges from red through orange, yellow, green, blue, indigo to violet (some people can see into the ultra-violet [UV]). Consequently our visual view of the world is limited compared with that available to other animals which can see further into the electromagnetic spectrum.

Typically, many can see ultra-violet, so their view of a simple flower like a Dandelion is quite different to ours:

[It is important to understand the difference between recording/seeing ultra-violet and seeing colours produced by shining UV on some objects (e.g. glowing teeth and white shirts in a nightclub) – this is fluorescence and results is the emission of light by a substance that has UV absorbed light or other electromagnetic radiation or other electromagnetic radiation, typically UV.]

Insects are particularly sensitive to UV and many plants have evolved patterns involving this colour.

Many birds can see UV too and use this in their plumage, particularly males, so what we see is quite different to what a hen bird would see:
