Trey Rogers took this photo of Denver’s City Park at sunset in June 2009. He used a Nikon D70s camera with a Nikon Nikkor Micro AF 105mm lens, ISO 320, f/2.8, 1/50 sec. (resting on a flat surface). Sharpness, brightness, and color ­saturation were slightly enhanced using Nikon’s ViewNX2 software. Rogers is a partner with Rothgerber, Johnson & Lyons LLP. His practice focuses on public law.
