Abstract

When a two dimensional light shape is projected onto a moving photo-sensitive receptor the resulting image may be read by the eye/brain as a three dimensional image. If this phenomenon is combined with a mechanical drawing machine and mathematical figures, it allows some exploration of the following topics. 1. The perceptual process of reading these non-figurative light drawings as 3D photographic images. Particular reference is made to the expressive use and control of tone and colour. 2. The aesthetic differences between images created by line and by light. 3. A philosophical question may be put. A photograph usually represents ‘reality’, do we read it differently where no real object existed?
