Description

I’ve finally completed my year-long project! This analemma shows the sun’s position from my location at 21:15 GMT (4:15 pm local time) throughout the past year. It traces out the figure 8 pattern as a result of the earth’s tilt and eccentric orbit. The foreground shot was taken in late spring, and each solar exposure was taken using a Canon 60D with 18mm lens and a variable neutral density filter set to about ND1000. The weather was mostly cooperative except for a few gaps here and there, notably just before the summer solstice (upper right) and winter solstice (lower left).
