This note extends the earlier 'Manual of perspective for lighting engineers'1 to discuss the effects produced when the observer is in movement, showing how the dynamic perspective changes which result are powerful and subtle means whereby the observer perceives the distances and positions of objects, his motions relative to them and the movements of other objects themselves in motion. Some practical conclusions are reached relating to building layouts, and to vehicle control in the air and especially on motorways by day and at night and in fog; suggestions are made for aids to perception.
