When Henri Cartier-Bresson talked about the "Decisive Moment" in the process of image capture, it must surely have been applied here, as the storm is just clearing, Adams chooses carefully when to press the shutter. In an instant the moment is captures as the storm clouds move away in the top of the frame leaving the fresh snow untouched behind them. The use of the greatest depth of field creates breathtaking clarity and interest.
