I constructed this one night after discussing with Christopher how we might produce the image. I was alone, bored and had time on my hands. The trick is to keep the lighting and the camera still during the shoot and make sure not to move any of the furniture. The lighting was adjusted for each shot, using a flash meter, so that the exposure was as uniform as possible as I moved between chairs. The screen grab shows how the images were placed on layers with black masks which allowed the correct part of the image to be painted in on a graphics tables. I am sure there is a cleverer way to do it and a model with better posture but you work with what you have got.
