I am back from a two weeks+, 3400 miles road trip, mostly in Utah and Colorado (but I also photographed in Nevada, Arizona, California and New Mexico). It was productive, but tiring, especially on the first week, when I did a lot of night photography, taking advantage of the new moon and first quarter. In the days of film, sensitivity was too low for stars (unless you wanted trails, which I am not that interested in), so you got to sleep between dusk and dawn.
This one is Double Arches in Arches National Park, lit with a camping lantern. Photographed on Canon 5D mk 3 with Nikon 14-24/2.8 lens. Main frame 30s ISO 6400, wide open. Although not strictly necessary, I blended it in a secondary frame exposed at 4min ISO 800 to reduce noise in the arch.
