Another shot from Canyon Lands Utah. An approaching sand storm threatened to end our photo session, and I hurriedly took a few shots of the dead tree perched on the edge of the cliff. The dust softened the scene quite a bit, but if we had had a clear sky, the shot would not have had the quality that resulted. In bright sunlight, higher contrast would have resulted, with washed out color every where. The dust storm actually enhanced the quality of the light.
