NOTICE: Tracking the Light was ‘off line’ for several hours during July 14 and 15th, 2013 as a result of maintenance to the host-site. Tracking the Light should now be functioning normally. Brian apologizes for any inconvenience.
Kodachrome was the best medium for photographing the rising sun.
I made this photograph with Mel Patrick and T.S. Hoover on the morning of September 4, 1996. We were positioned on the former Denver & Rio Grande Western at the aptly named CTC siding called ‘Solitude’ (population zero) in the desert east of Green River.
Wild fires in Idaho had polluted the air with particulates. During the day this was only barely noticeable, but it made for stunningly red moments at sunrise and sunset since the particulate matter acts as a filter and alters the natural spectrum of sunlight.
Since sunlight passes through more atmosphere at sunrise and sunset than during the height of the day the filtration effect is accentuated.
Kodachrome had two advantages when working with this type of filtered light. Firstly its spectral sensitivity made the most of the red light. Secondly, the inherent quality of the film’s silver grain structure preserved the outline of the sun despite extreme overexposure, while the latitude of the film allowed for an exceptionally broad range for exposure.
Other than the particulate matter in the air, I didn’t use any special filtration to make this image.
