The Turbulence series (images one - six) has gone through several iterations prior to finding an effective technique for creating the work.
The initial piece is created on the computer and then printed with archival pigment on an ink jet printer at 70% of the final shading density that I am trying to achieve. Then - the borders of each of the different shading zones are lined with graphite to create a softened boundary between the shaded segments. The last stage is to brush each shade zone with several layers of a Sumi Ink wash to build the color to the desired density. Other works employ lens-based media and explorative sketches.
