Every now and then, you have to stop and wonder "how is this possible?"

How the holy hell do you make a camera lens /that/ shape? And what the 
heck is holding the camera up??

This looks shopped.  I can tell by the pixels and from having seen 
quiate a few shopped images in my days.

If it was a synthetic image, would it have this much chromatic dispersion?

I still can't figure out how they did this...

  That word is almost meaningless because everybody uses it with a different
meaning.

  If it's a composite of several images, I would definitely categorize it
differently than something that has outright image manipulation. A composite
contains solely original image information which has not been manipulated;
it's just that different images have been stiched together (and possibly
blended) in order to form a contiguous whole.

  Of course if the original images were not in that fisheye perspective
shape but in a more regular perspective and were then distorted in
post-production to get that image, then it becomes a case of being
slightly heavier image manipulation than a mere composite. However, even
in this case I wouldn't classify it as outright fakery (which is what
"photoshopped" usually means).

>  I can tell by the pixels

  Please elaborate.

Something has been done to it, since the image claims it has been taken by a
Pentax K10D, which is a 10.75MP camera.

I'd guess it was a panoramic shot, maybe taken by a very high resolution camera
(since edges on the magnified parts are as sharp as those on the shrunken
parts), then conformally transformed (since there are a lot of straight lines
going to circles and other straight lines staying straight) scaled down and
JPEGged.

Don't know PhotoShop well enough to know if it will do the conformal
transformation. You might need something like Matlab.

Yes, but not in this case.  It's stitched together from multiple images 
into the appropriate projection.

Google Earth is fun.

The photographer was standing on the Pont de Bir Hakeim, and I'm now sure the
photo started off as a panorama.

Oops! You can read the bridge name from the plaque on the pillar in the
photogaph. In Google Earth, the plaque on the side the photographer took is
mirrored.

Hint: When an image file has "projection" in its name, it /might/ be no 
actual photograph at all, but the result of some postprocessing...
