Vertigo
Vertigo, photo by Harold Davis. View this image larger.
I lay down at the bottom of the spiral staircase shown in After the Wedding. With my tripod fitting clumsily in a tight corner of the stair, I used my digital fisheye to take a vertiginous photo up the stair well. In Photoshop, I layered in an extension to the hallway and replaced the skylight at the top of the stairs. Finally, I duplicated the image and flipped it horizontally. I pasted the original and the flipped version together to create a symmetrical, but twisted, abstraction.
