UV, visible and IR US currency

UV, visible light and IR US currency

A while ago at Grendels, I happened to discover an odd characteristic about US currency in infrared: it has special markings! So I decided to do a proper photo shoot using as many interesting sources of light that I had around my home.

These are only a few bits of the spectrum. I wonder what surprises await in other, less accessible parts!
