This is a very straight-forward simple shot of a reflection, however NO ONE on earth will be able to duplicate it. The rain came a few days before I was there and filled this little indentation on the rock surface and then the clouds came in at Sunset and illuminated the sky. All I had to do was open the shadows and increase the vibrance in PS.

Great shot! I have almost that exact scene but with the Milkyway reflected in the water. You are right about getting there to shoot right after a rain when all of the rock pockets fill up with water.
