I was photographing an air show in Anchorage, AK featuring the Blue Angels. They came through in tight formation going almost straight up with jet trails. It was somewhat cloudy, so I punched up the colors and jet trails a bit with the Topaz Clarity filter in PhotoShop. Nikon D750, ISO 400, AF-S Nikkor 70-300mm f/4.5-5.6 G VR Lens @ 300mm, f/11, 1/640 sec.
