Full spectrum
This image requires some explanation. The blue colour of Blautopf is induced by small silicate particles that, thanks to Rayleigh scatter, predominantly scatter back blue light to the surface. Full spectrum had very intriguing effects:
1. Outside of the water, full spectrum (and therefore infrared excess in the leaves) dominates at this white balance
2. Below the water, there is almost no infrared emission. Water is much more absorbant in the IR and Rayleigh scatter is highly dependent on the wavelength!
3. At the water surface, due to the wavelength-dependency of the refractive index, there is an almost complete reflection of the infrared light. Hence, the reflection appears slightly brighter (and whiter) than the actual trees
A quick demonstartion of the effect of a variable ND filter on a full spectrum camera. (SSOC)
Darker ND gives more IR character, with quite rapid change in the first bit of adjustment.

Taken on a miserable rainy day from under an umbrella with a full spectrum converted Lumix DMC-GF3 fitted with a 590nm infrared filter on the lens.
The lakes were flowing through heavily with the amount of water coming off the surrounding land.

Shooting landscape and suddenly there were parrots. Didn't have time to change settings for their flight.

While out adventuring one day I ran across this old building. If you know me, you know that one of the things I love is when nature reclaims things. So of course I fell in love with this building right away. Then when I saw how it looked with my infrared camera, well, that sealed the deal!
This image was taken with a full-spectrum converted camera, with a 470nm infrared filter. It was shot in RAW and processed in Linux using RawTherapee.
