From cityscapes to country roads, Edward Levinson captures even the smallest movements of nature through the eye of his pinhole camera.

In his current exhibition, "Shadows Talk," Levinson focuses on the interaction of light and shadow. Under his spell, these movements, part of the natural progression of time, seem to dance in his photographs. He has his pinhole camera to thank for that, he says.

Compared to a regular camera, a pinhole camera is primitive, just a box with a tiny hole, having neither a viewfinder nor a lens. Because pinhole cameras don't have a shutter, they have longer exposure times -- from five seconds to up to 30 minutes per shot, depending on the size of the hole.
