There is nothing less interesting to me as a landscape photographer than a bright clear cloudless sky, but add some clouds and marginal weather with interesting light and wow, some magical images can be made. A great example of this is my Bison and Crestone Peaks image where the sun lights up the layers of clouds formed from an inversion and a clearing late Spring storm with fresh snow on the peaks . Earlier in the morning the valley was blanketed in fog and I was able to make some interesting images but as it started to burn off, this amazing scene was revealed. Clouds can add a dynamic element to any landscape and can make any image truly unique.
I will offer two additional examples, a black and white image of amazing cumulus cloud build up over the Chiricahua Mountains in Arizona in July, and early morning clouds over the Tall Grass Prairie Preserve in Oklahoma. Without the clouds my camera would have stayed in the bag.
