Green Artifact

Green Artifact, photo by Harold Davis. View this image larger.

This is a photo of the Marin Fountain in Berkeley taken at sunset with my fisheye lens. I was surprised to see the lens artifact in the photo. Although I did stop the lens down all the way to f/22, in response to a number of questions, there were no filters used (I actually don’t have any filters that will fit over the complicated optics of the 10.5mm digital fisheye).

The lens artifact reminds me of a green alien fish sliding into the fountain.

    I believe that the green is not an artifact, but a “green flash” exaggerated by the fisheye. Green flashes are relatively rare occurrences that may appear at sunrise or sunset. Information and links to picture may be found at

    You were extremely lucky .
