I should say it is the most complicated photograph I have ever made. It shows position of the Sun on the sky in the same time of a day during one year…

Analemma - a trace of the annual movement of the Sun on the sky - is well known among experts of sun-dials and old Earth’s globes as a diagram of change of seasons and an equation of time. Between August 30th 1998 and August 19th 1999 I have photographed the Sun 36 times on a single frame of 60-mm film. The pictures were taken exactly at 5:45 UT (Universal time) of every tenth day. Previously, the position of the Sun on the sky was calculated with computer as well as optimal moments of time for taking each of the exposures. However, my success was strongly limited by the weather. Nobody can guarantee fine weather every tenth day even for a few minutes. Approximately, there are 120-170 sunny days a year in Crimea. That made me sure that my aim could be achieved. To do the job, the camera must stay fixed during 12 months. It was difficult to find such a place where the camera would be safe.
