Timna helped me think of black and white things and pictures I might want to interpret pieces of. She suggested Edward Weston, and pointed me to the stunning nautilus shell. I used an edge of it yesterday, and the center of it today.
I had thought I wanted to interpret entire images in (more or less overlapping) circles, and then attach them together to make an interrupted version of the original. But I am less sure of that idea. Maybe I just need to experiment with how to get layers of black and white and gray together.
After the snowstorm Thursday, all the world outside was shades of gray and white, and rain-soaked black. The snow was still stuck to everything; tree branches and telephone wires and fences and ponies. It was very beautiful. And made me want to make circles of it.
