No time this morning to visit Contra Loma or Big Break Regional Park as I had to leave for San Francisco very early. Luckily a great colorful sunrise presented an alternative for some great photos. The the time difference between the first photo and the second is about 5 minutes and about 10 minutes between the first and last.
All photos were taken with my Sony SLT α77 and Tamron SP AF 90mm F/2.8 Marco 1:1 lens, using Aperture mode, with a setting of f/8, White Balance set to cloudy, ISO to 800 and 3-shot bracketing with +/- 0.7 EV. No post-process adjustments were made to the photos.
