Okay, hold the phone, because these photographs by Abelardo Morell are nothing short of amazing. The reflections on the walls weren't put there via Photoshop or projector, but by a photography technique called camera obscura. Basically the rooms in the photos are completely darkened while a small pinhole is cut through whatever curtain is blocking the outside light. That pinhole exposes the view from the window onto the opposite wall. That's a watered-down explanation of the centuries-old technique; more on camera obscura here. Pretty cool, huh?
