Willem de Kooning (1904-1997) was a Dutch American abstract expressionist who, after classical training in fine arts, developed a very recognizable style. His process involved much addition and subtractions with paint and charcoal. He moved lined, added things, erased bits, painted over other bits to end up with a piece such as woman v.
Neil Callendar, my professor from drawing one and two had us do a project inspired by one of Kooning's drawings, Two Standing Men. He was inspired by how the visible movement and re-working of the hand gave the feel of the drawing happening over time.
The idea is that the base is still but then there is something on it that moves or changes over time. So he had us draw a chair, a really solid and clearly defined chair with different objects in it that were drawn over or erased by different objects.
Here's a slideshow of the drawing at different stages. It is really interesting to look back and see how it developed over time.
Mine turned out looking like it was created over a long period of time, which was interesting compared to other drawings in the class which looked like they were created in just a few minutes or rendered on the computer.
This project branched out into another project, which is too lengthy to add to this post. So I will post about it later.
