Writer and portrait artist Thomas Leveritt took to the streets with an ultraviolet camera to reveal people’s sun damage under his special lens. The camera shows the not-yet-visible effects the sun has on skin.
There’s no visible light in this photo. Shot with a B+W 403 filter and a B+W 486 filter. The resulting wavelengths, I believe, are shorter than about 250 nm and longer than about 850 nm. This is the result after puttering about with white balance and colour balance.
On another note, it is considerable difficult to focus ultraviolet wavelengths and infrared wavelengths together.
