The photograph is of a temple which has a hole for light ray to be falling on the ground. It was built during the Pallava's (the things you learn when you travel!). And if you go to Kanchipuram beware of the heat, temperature touchs 35+*C!
The reason I’ve put it here is because it’s a photograph that has good contrast. The image has light and dark areas right next to each other, all over the photograph.
