Light Painting is a photographic technique in which exposures are made usually at night or in a darkened room by moving a hand-held light source or by moving the camera. Check this link to know more about Light Painting.
Today morning I tried this with my Sony DSC H7/B camera. I used a small Torchlight and some light as light sources. I was surprised after seeing these photos. Please check some of these photos here and do comment.
