Boundary Layer, 2018, is an ongoing series of unique cyanotypes that use sodium carbonate (washing soda, it bleaches the cyanotype pigment) as a tracer to record water flow over a surface.  They range in size from 38x50 inches to 38x120 inches. Each grain of sodium carbonate that hits the cyanotype leaves a streak as it dissolves. The streak is a vector, it records direction and velocity of the flow at a point. The process of making these is a dance. I start with a developed and dried cyanotype, as water starts to flow over the surface of the paper, it warps and buckles, creating a topography that channels the water into a complex anastomosing patterns. With the water flowing over the piece, I start moving around it, tossing the sodium carbonate grains up in the air where they are picked up by currents and randomly distributed onto the piece. I only have about 30 to 60 seconds between the time the first grain hits to when I need to start washing it off. I don't have any time to think. The final piece are a physical record of these transient movements - water, air and body. It's scientific in this way, (although obviously without the rigor) the transformation of complex phenomena into data.
