Thanks, guy! It was thunderstorms in the afternoon most of the days, except for the last day where they were active all day long. Most of those pictures are not tweaked and show what it really looked like, except for a couple where I saturated them a bit to bring out the clouds from the RAW image. That picture in the Alabama Hills with the bluish clouds was really how it looked. We were shooting toward Mt. Whitney and the tops of the thunderstorm cells hanging over the Sierras were illuminated by the morning sun. I turned around and saw that the clouds were producing a rosy red color to the nearby rocks and bluing up the clouds too...it was beautiful! The last shot was pure serendipity. A thunderstorm cell to the east was blocking any direct sunlight, when suddenly a break in the clouds allowed that one sunbeam to shoot straight down from overhead and hit Mt. Whitney directly....how cool was that?
My favorite pic is the third shot at North Lake west of Big Pine. I need to tweak that photo to tone down the brightness of the clouds while maintaining the amazing colors from all that warm light. You can see a couple of rings on the surface of the lake where trout were jumping out of the water all morning long. We're going back late next month on a trip with lots of family...should be pretty cool as it'll include Yosemite in the itinerary.
