Having had some rising temperatures (+8°C) one week ago, snow returned to Karlsruhe the day before yesterday... I even managed to go out in the cold for taking a handfull of pictures, with maybe two or three keepers.

For the picture posted today, I decided to introduce a new tag called "Colour Mapping"... I'll use this one for tagging pictures that are post-processed with a technique I saw from David J. Nightingale. As far as I could "reconstruct" this technique, an image is desaturated in a first step using a channel mixer (or whatsoever) and is getting individual curve adjustments for its single colour channels, c.f.
