Pinhole Camera at Virupaksha Temple
This is one of those temples where you can see the gopuram’s (temple tower) inverted image in one of the rooms in the temple. Quite a marvel to see how advanced are ancient folks were in science and technology. The replica or shadow of the tower of Virupaksha Temple falls inverted inside the wall of the temple through a lens like hole structure. It is called Pinhole Camera System or Camera Obscura.
What is Pinhole Camera?
A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole – effectively a light-proof box or room with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box or wall of the room, which is known as the camera obscura effect.
