7:45 AM. The light was changing very, very fast now. The sun had risen over the tufa field, which greatly amplified the contrast of any scene with the tufas. This shot was taken moments after the sun struck the tufas, and they still retained the warm glow of the first light. Again, bracketed exposures were used to hold dynamic range. 1/10 sec, f/8. This image was actually desaturated a bit as the colors were quite overpowering in the original image.
