My most visited viewpoint in Big Bend is the Desert Mountain Overlook. I stop here every day as this is the closest view to where I camp at Cottonwood. It also has a several possible compositions in different directions. It has a great view east to the Chisos that is good for sunrise as well as sunset. Across the road are a couple of views west and south along the Rio Grande and the Sierra Ponce. Those varied possibilities make it always a place worth checking out.
It also has a good view of the entire sky. Meaning when I leave the campground every morning, I always drive here in the dark. With a clear view of the sky I can judge what the clouds are and use that to help me decide my morning location.
There are several great possibilities within a 15 minute drive so by stopping here I can judge the light and then pick the best of several possible locations. Sometimes that means driving a little, other times it means staying put.
This was an afternoon and it was a chance to photograph clouds over the Chisos in the afternoon light. Again, that afternoon light offers a view with the Chisos front lit. Add in some big sky clouds and you have a great shot.
This is very different from the morning view here with the back lit peaks that truly earn the name "Ghost Mountains".
With the clouds like they were I went with both color and b+w, figuring each might be good. The color was ok, but honestly the wider view I was able to make with my DSLR at 17mm was better. However the b+w image had something the digital did not.
Here is that shot on Efke 25 with DR-5 processing.
