Yesterday morning here in Patagonia my photo tour group had the most amazing lighting on the famous peak, Fitz Roy. Clouds obscured the sun at sunrise, but a half hour later those same clouds created dappled light on the entire range of the southern Andes Mountains. It was truly something to behold. This is an 8-frame handheld panorama. I used a 100-400 set to 214mm, and my settings for each frame were 1/6400, f/5, and 400 ISO. I could have slowed the shutter, but since depth of field was irrelevant in this shot (because all the elements were so far away), the shutter didn't matter except that it was fast enough for a sharp image. And the lens aperture also didn't matter because the scene would be sharp at any aperture. I've not seen anything more beautiful than this in all my travels.
