To create his camera obscura images, Morell covers windows with black plastic and pokes a 3/8-inch hole in the material. The outside world is projected upside down onto a wall, and he then uses a view camera inside the room to document this confluence of interior and exterior spaces. More recently, he has employed a diopter lens—an optical tool that significantly reduces exposure time and increases the brightness and sharpness of the image. Photographing with a digital camera reduces exposure time even further, from hours to minutes. The passage of time is nevertheless made evident in this image in the blurred numbers seen on the bedside digital clock. In these images, Morell also used a prism to change the orientation of his projections from upside down to right side up.
