"Instead of a single long exposure to record the motion of the stars as the Earth rotates on its axis, the picture is composed of 90 consecutive images, each exposure 90 seconds long. Digitally stacking the individual exposures then reconstructs the star trails. It also creates a ghostly, semi-transparent figure of the photographer who was captured standing on the beach in only one of the exposures."
