Using the same original image I selected 'Solarize' from the effects menu. The results look something like an oil slick on water. I converted the solarized image to black and white and discovered this is a great way to isolate the basic shapes and light patterns in an image. Even though it's now in black and white I was still able to adjust the appearance of the image by using the color slide bars you see at the bottom of the Elements window.
