whats going on here? photography.
Today I set out to make some coal dust, very fine dust, sieved many times to add to my black paint for the final of the 'inchoate' series, called nemesis. The ust itself is a fascinating and mysterious force. I played around with it and photographed the results.
What struck me about this operation was how tone, figure, ground, shadow/ light and ultimately metaphor all emerged quite spontaneously from the process.
