My current series of time exposure photographs of clouds actually began over twenty years ago, in 1982. I had been making time exposures of wind and water, and occasionally there would be clouds in the photographs that would also be recorded. The long exposure gave a wonderful rendition of the movement of the clouds, and I tried a few exposures of developing thunderheads in the summer of 1983, but then the work lay dormant for almost twenty years while I worked on other projects. In 2001, I picked this work up again, and began a serious study of the movements and shapes of thunderstorms. Tucson is a wonderful place for thunderheads in July and August, as the summer monsoons build over the mountain peaks around town, and this series has developed into a seasonal project for me. For two months of the year, I become what Thoreau called the “inspector of thunderstomsâ€?. The extraordinary shapes assumed by the moving clouds continue to amaze me, it reminds me of the child’s game of finding faces or animals in the shapes of clouds. Besides my work in Tucson, I have also photographed clouds in Utah and Colorado.
