Here is my first attempt to capture... I took these images some time ago, now are finally processed.
The lens I used was Tokina 12-24/f4 (Nikon D200), at 12mm focal length. Images are not cropped, sun is behind & in the middle of flagpole at bottom right corner.

I converted the original image to lab-color mode. Then took "a" (green–red component) and "b" -channel (blue–yellow component) to process at Photoshop. These two channels contain only color info of original image, luminance I have discarded.
I could see a bit difference in the processed images (the radius of darker arc). I guess this indicates of different radius of different colors in rainbow. There might be also several other ways to enhance images, this one I usually take. I do not see any indication of 4th order bow...
