These pictures were taken by photographer Tokihoro Sato.
Fairies or not?
Actually, here's how he did it:
"Using an 8 x 10 inch camera fitted with a darkening filter, Sato makes lengthy exposures of up to two hours. During that time, he moves through the landscape, pausing periodically, counting to ten, with a mirror to reflect sunlight back at the camera. A reflective triangular frame is mounted around the camera lens so he can see whether the light is being accurately reflected at the camera. Because Sato remains in slow but constant motion throughout the long exposure, he is invisible in the photograph. Only the points of light testify to his movement. "
