This was a blend of 2 exposures to capture the broad dynamic range that I could see. I set up my camera along the shores of Glacier National Park's Swiftcurrent Lake. Still reflections are unusual, so this calm evening helped reflect the mammatus clouds that streamed overhead. Glacier NP is often referred to as the Crown of the Continent, and I thought the cloud formations hovering above Grinnell Point gave the image a more literal interpretation. While the original color shot was dramatic, I thought the clouds and separation of forms and textures made for an equally engaging B&W.
