Walking the dog recently in precarious weather on one of our local beaches. Intermittent showers and strong winds ruled the day, but the sky partly cleared to reveal this rainbow. Not exactly a spectacular example but the cloud shapes appealed to me making me wish I hadn't left the Nikon at home. So I resorted to my iPhone 4. Three exposures merged in CS6 Photomerge.
"The best camera...... etc.etc."
