Photographer:

Craig Lent

Location of Photo:

University of Notre Dame

Date/Time of photo:

October 28, 2012-October 28, 2013

Equipment:

Canon 20D DSLR and fixed tripod

Description:

The photo shows the sun in the sky over the Golden Dome at the University of Notre Dame, recorded at the same time of day during the course of a year. These forty-one solar images were made through a solar filter at 10:07 AM EST (± 5 sec.) while the camera was kept oriented in the same position on a tripod. The foreground image was first taken from the same camera position without a solar filter near sunset, so the sun was out of view, and combined with the solar images. To my knowledge, this is the first analemma photograph that encircles a terrestrial object. It was necessary to carefully calculate the time of day at which this would work.
