I love the color of these flags against the dark blue sky.  The breeze gave the flags a nice sense of motion as well.  I used a circular polarizing filter to darken the sky, then punched up the saturation, and contrast in photoshop.  I also cloned out a couple of additional cables which I found to be distracting.  Overall I love the colors in this shot.  ISO 100 f5.6, 1/500
