Light painting is a photographic technique in which camera kept in a dark room (most often) with the settings for long exposure and move the hand-held light source or camera that creates an optical illusion. In many cases the light source itself does not have to appear in the image.
I first came across such image in a PhotoStream of Abhijith. Recently I came across a wonderful artist who is a real professional in Calligraphy and Light-Writing. He is Julien Breton and it is worth visiting his PhotoStream in Flickr.
This is a hundred year old technique used by Pablo Picasso and in recent time its popularity increased due to some of the recent advertisements.
After watching a few such PhotoStreams in Flickr, especially the work by Julien, I fet myself to attempt for such experiment. My attempt was to assess myself the talent and technique required for such a wonderful art. These are my results and can easily conclude that it is not an easy task to master in this art. This made me to admire the work of those talented artists.
