You'll have to see this ( http://latentsouls.blogspot.com/2009/03/digipin-hole.html ) earlier post to understand how these photographs are taken :)
Just could not stop taking pictures on my digi-pinhole camera. This time shot at 100 asa and on a tripod. Tried a lot of early morning, noon and even late night exposures. It gives an amazing painting like effect with all the great colors you can imagine.
