ONLY WAY to get a double rainbow like THIS is for the light to go through first one prism, then another prism. Otherwise the water particles would only seperate the light once, resulting in the typpical rainbow we are used to seeing, starting with one color, and ending with another. This one ends with the same color it starts out with. Look at the bottom left edge of the photo to see the clearest part of the rainbow. To do this, the light HAS TO be passing through a lens of some sort before it gets to the cloud layer. I have had such a problem uploading this photo. It is as if something doesnt want me to show this. So i am going to keep plugging at it until it finishes loading.
