To create the piece, I built a table top construction with a clear acrylic top. I drilled rows of holes in the acrylic and suspended wire in the near ground through the holes. Behind that I suspended colored craft thread, experimenting with a progression of colors across the picture plane.
I lit this construction and photographed it against a gray seamless background. In the process I made a number of experiments with depth of field until I got the right balance of in-focus texture with out-of-focus color field.
