Mount Rainier in IR

Mount Rainier National Park, Washington

Infrared (IR) film or sensors can provide unusual black & white or color renditions of a landscape.  Skies will turn black, green foliage will be rendered white, and the resulting image can be striking.   I was fortunate to have some cirrus clouds over Rainier; they added much to the composition.
