A Canyon Sunset from Desert View

We watched the sunset during our Grand Canyon trip last month from next to the Watchtower at Desert View near the eastern entrance to the Grand Canyon.  I was hoping for a more colorful sunset, but the nearly completely overcast sky limited the colors present.  Here are a couple HDR combines, the first looking west into the canyon below the main visitors center on the South Rim.  I combined 5 exposures at 1 stop offsets centered on the metered proper exposure.  The shortest exposure which allowed the brightly lit sun to be visible in the sky was 1/45 seconds at f/6.7, ISO 200.  The longest exposure was 1/3 seconds at f/6.7, ISO 200.  All with my 24mm lens and the camera was on a tripod.

This view upriver produced some spectacular colors.  The view of the river in the bottom of the canyon was also quite spectacular.  This HDR combine used 5 exposures from the shortest of 1/30 seconds at f/6.7, ISO 200 to 1/2 seconds at f/6.7, ISO 200 with my 24mm lens on my 70D.
