Spent a few days in Yosemite a couple of months ago. Went in the winter time to get storm clouds, snow and any other interesting effects that I could find. However, no storms, no show, no rain and damn little water. Ended up restricted to mostly reflection shots.
Half dome at sunset.
The bridge near the lodge.
The three brothers. (A little in-camera HDR on this one.)
El Capitan from the river.
Climbers asleep half way up El Capitan. I had my 400mm with a 1.6 extender to get this one. If you look carefully you can see ropes hanging from pitons above the upper left of the shot and other ropes hanging down from the tents.
