What is This? Camera-less Photography

These photographs are luminograms made in a traditional dark room using light sensitive silver halide paper, a torch and transparent objects. No camera or lens has been used, so this is purely painting with light. Since art is made in the mind of the viewer, it is very interesting to observe one's own responses when viewing these images, as the mind search to make sense of what the object is. The subject of this series has become perception.
