About half an hour after I took the previous blog entry image, I was here on Sunday evening, farther down the Icefields Parkway, at the shore of Lower Waterfowl Lake. The peak is Mt. Cephren.
The Sun had set and the sky was now filled with the purple glow of twilight marking the beginning of an exceptionally clear night.
Capturing this scene as the eye saw it took a stack of 7 different exposures, combined in what is known as a High Dynamic Range image, that blends the shadows details in the foreground without losing the subtle tints of the bright sky.
