While discussing perspective, Tom explored the 'cone of vision', and also the effects of distance and viewing point on how things appear.

These three Styrofoam heads have not been moved, but the VIEW POINT has. They are not equal distance apart. In the picture on the LEFT there are four boxes spaced evenly apart just as in the photo above it. The third from the front has no head on it. The rear head is twice as far from the front one as the second one is.

With the use of boxes, hangers and manikin parts Tom pointed out many perspective phenomenon in typical portrait arrangements. Here we see how the 'body' represented by a box is clearly tilted, yet when seen from above and to the higher side, it appears horizontal.
