Lake McDonald, Glacier National Park

The perfect sunset was unfolding in front of me. I was setup in plenty of time on the shore of Lake McDonald in Glacier National Park. The bright opening in the clouds promised to allow the low setting sun to perfectly illuminate the bottom of the storm clouds that filled the balance of the sky.
 
Unfortunately, the cloud hole was obscured by more distant clouds when the sun reached this location. Using a Singh-Ray 82mm Slim Vari-ND Filter on a step-up ring caused mechanical vignetting at focal lengths wider than 32mm, but allowed a water surface-smoothing 30 second exposure. I like the cloud reflections in the water.
 
Manual HDR was used to control/balance the brightness of this image.
