Winter white

The empty space on the right is actually a lake, iced over and rendered invisible by the mist and snow.

 

This IS a color image, btw -- but the only colored things in the scene are the tree trunks, and they're more gray than brown. Still, the subtle browns and the greenish and bluish gray hues give this a certain depth and life. You wouldn't think so, but they do. I tried a B+W conversion and the resulting image was just flat.
