When driving through the Mountains one encounters numerous snow-melt water falls. On my trip through the San Juans, I attempted to visit Yankee Boy Basin near Ouray, CO to photograph some wildflowers. Unfortunately it was raining pretty hard, and although normaly I would venture up the precipitous rocky 4WD road anyway, I encountered 3 vehicles coming the opposite direction with expressions of life-clinging fear, admonishing me to turn around because the road ahead was washed out. So, when I turned around and started heading back down I spotted this waterfall. Really, it was nothing out of the ordinary, but the "M" shape of this section of the falls struck me, so I got out of my car with my plastic-covered camera, set up my tripod, and fired away (I think more than anything I didn't want to leave the basin empty handed). Because of the low levels of diffuse light, the wet foliage appeared extra vibrant.
I didn't really need to process this as an HDR, because I was able to capture the full-dynamic range in one exposure... but I like the texture and depth created with the merged exposures. Created from 3 RAW images in Photomatix Pro and Photoshop CS5.
