ultra violet

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.
