Well, for one, I know that this phenomenon is known as a "double-rainbow" where a second fainter rainbow appears with the colors of the spectrum in reverse order.
The light and dark may have been done using selective metering or possibly a graduated neutral density filter to really hold back the exposure of the photograph.

| I've seen this photo before. double rainbow is real, but the bright semi-circle under the main rainbow is not, most likely selected that area in Photoshop and simply increased brightness ther and/or decreased brightness outside. |

EXIF is intact. Taken with a 10.5mm Fish F2.8 at a shutter speed of 1/250. Camera was a D70. Edited with Adobe Photoshop Elements. Taken/edited in February 2006. I don't think a lot was done to this image. Can Elements de-fish???

No filter needed. It's a natural effect when you take a picture of a rainbow, especially when there is a secondary rainbow, for the upper sky to be darker then the sky under the rainbow. I will post an example of a rainbow that I took in Hawaii, I had the same effect.

| it is very possible for the under part to be brighter, especially if maybe the sun just happened to poke out of some clouds long enough to make this. The angle of the shadow on the tree and such looks like that is how it happens. Very beautiful image. |

You will need two pots of gold instead of just the usual one.

Both the double rainbow and the brighter area inside the rainbow are real, but most likely the brightness has been enhanced somewhat.
Apart from the explanation of rainbow physics, the wikipedia article ( //en.wikipedia.org/wiki/Rainbow ) has similar, though less dramatic, images.
[ edit ] and yes, the underside of any rainbow is always brighter. I forgot what this phenomenon is called.

This should answer most of your rainbow questions.
