(© Ian Plant) During my recent three week trip to the Patagonia region of Argentina and Chile, I had one of the most productive shoots I have had in a long time. Patagonia was exceptionally generous this year, and I came away with a lot of images that I am really happy with. Sometimes, there was so much going on, it was hard to concentrate on any one image. Such was the case the morning I took this photo of a rainbow arcing over Paine Grande in Torres del Paine National Park, Chile. I was busy photographing some beautiful light in a different part of the sky, when I noticed this rainbow beginning to form. I wasn't about to abandon my carefully chosen composition, so I watched anxiously as the light peaked before me, and as the rainbow progressed to my left. As soon as the light in my first photo started to fade, I jogged along the lake shore to find a still reflecting pool for the rainbow. I quickly found something that seemed adequate, and managed to snap off two shots before the rainbow and morning light faded. Just in the nick of time!
About the image: "Morning Glory"—Torres del Paine National Park, Chile. Canon EOS 5D Mark III Digital Camera, Canon EF 16-35mm f/2.8L II, ISO 100, f/11, 3.2 seconds. A polarizer filter is a "secret weapon" when photographing rainbows. Turn the polarizer to full polarization, and the rainbow will mostly disappear, but if you turn the filter just slightly past no polarization, you will make the rainbow look stronger and the colors will really pop. Experiment to find the ideal position for the filter—trust me, you'll know it when you see it! Rainbows at sunset or sunrise (as was the case here) tend to be less colorful, as red light dominates because of the low angle of the sun.
