This is not a crop but with a telephoto lens we seem to be seeing from inside this brilliant rainbow. I made minor adjustments in Adobe Camera Raw and removed several houses in Photoshop Elements 9.

I shot this with a Canon EOS 50D camera and a Sigma 150-500mm 1:5-6.3 APO HSM lens. My settings were 1/400; f/10; ISO 100; 403mm.
