grand landscape showing layers

I took this picture at mission dolores park in mission district at sunset. I took this photo by taking individual parts of the park and putting it together on photoshop. I then changed the value of each layer therby enabling the eye to see each individual layer. I took it of this park to show grand landscape. This photo shows color because of the green, white, and blue. It also shows space because the green is positive and in focus while the white and blue is negative and blurred.
