Stormy Sky, Colorado

We had been in the mountains in Colorado for a few days, my wife to unplug from her busy schedule, and I was there to work and work hard. We were driving up this mountain road and I had found a cow pen that was interesting with a gigantic cloud structure above it that I was working on. Virginia called my attention to a cloud structure back to the south that was interesting, which I photographed next, and then i rotated the camera back to the east, where this beast was building. One of those very rare cases where everything was right. I made the photograph and we headed for our abode. I used a Toyo 45A camera with a 150mm Sinaron lens with a UV-15 filter on the front. Kodak E 100G 4x5 film. I later realized that I should have used black and white film so I converted it to black and white using Photoshop.
