“Star Trails” Created by Long-Exposure Photography As Earth Spins

Layered, long-exposure photos of stars “traveling” around the North Star create amazing images

 




An Australian photographer has combined time-lapse photography with long-exposure shots to create colorful “star trails.”

 

They look like computer-generated images, but they are actually real, extremely-long-exposure photos.

They’re created by keeping the camera lens open for up to an hour at a time, which creates a streak behind each star as it “travels” around the North Star.

Though they look like “shooting stars,” they only appear to be moving (especially fast near the North and South poles) because Earth is spinning on its axis.

The really cool photos are created when the photographer, Lincoln Harrison, stays out for up to 15 hours on a freezing winter night, capturing the entire 360-degree journey of the stars.

The series of long-exposure “still” shots are then layered on top of one another, creating a  circular rainbow of colors.

Harrison offers tutorials for those wanting to replicate his work.
