I dream in infrared...

...said Queensrÿche, and they were right. While the elderly gentleman on the "5 fingers" viewing platform atop the Krippenstein (Austria) watches the Dachstein mountains in his native spectrum, the photo was taken in near infrared (>720 nm). Longer wavelengths of light (or electromagnetic radiation in general) become less susceptible to atmospheric scattering, which is why even very distant objects are clearly visible in the picture. The cell walls of plants highly reflect infrared radiation while chlorophyll behaves completely transparent. Subsequently, vegetation appears really bright (up to blinding white) on infrared photographs.
