When I draw with the cristal image created by reflecting light, how far could I control the drawing? Am I drawing or are the circumstances of the surroundings sketching for me?
When a line is traced by the reflection of light without leaving a trace, when I let charcoal dust slide throught my hand and let is slip onto a paper surface - in how far can I let that sketch be created without interfering with it?
To draw and let draw without leaving an additive or subtractive trace on the surface.
To draw with the reflection of light visible only for a moment in time.
