New York-based photographer Eric Cahan photographs the sky, usually at sunrise or sunset, using a number of different cameras and filters, then takes the images through a multi-step printing process. The finished photographs are reminiscent of Rothko, by way of the psychedelic 1960s; like the Impressionists, Cahan writes, he aims to "create a window into a time and a place."
These photos are from Malibu, San Francisco, and L.A. See more of Cahan's "Sky Series" at his website.
