Carrie Mabee of Gould Evans asked me to take architectural photos of the new State Historical Society of Missouri building on Elm Street in downtown Columbia, Missouri. I knew the light would be the best mid-afternoon and set up my tripod in the park across the street. I used a 12-stop Haida neutral density filter to slow down the light entering the aperture and to achieve a wispy, dreamlike effect. This particular exposure was 53 seconds long. I also used a 24mm Canon tilt-shift lens for in-camera perspective correction.
