A camera obscura is a dark room with a hole facing a lit scene. The light rays entering from the hole, on hitting the surface opposite the hole, form an inverted image of the scene on the surface. This is the optical phenomenon at work in our eyes—the hole being the pupil of our eye, and the surface forming the inverted image, the retina. The retina transmits the image to our brain which thereupon gets inverted back. This dark room has now shrunk into a portable box that is the camera; a ready accessory for us to go around with.
My preoccupation with the camera obscura drove me to build these dark chambers of my own wherein I could witness the work of light.
