Date/Time of photo
Late March, 1997
This image was made with a 24mm lens and employs a technique called "the Shift," short for intra-exposure focus and aperture shift. First, the arch was focused on and rendered with a flash @ f/16 as soon as the time exposure began. Then, the focus was shifted to infinity and the lens opened up to f/2.8 for the remainder of the three minute exposure.
Here is Comet Hale-Bopp framed by the Keyhole Arch and about to set beyond the silhoutte of a chalk pyramid at Monument Rocks National Natural Landmark.
