From our Spring '09 snowstorm.
This is one of my favorites. I love the texture of the snowmelt rivulets and the contrast of the twisted aspen tree and its shadow. It's practically B&W to begin with, but I went ahead and desaturated it to increase the effect. The ONLY alterations here are de-saturate and global toning/contrast. Not even any crop.
