Actually Bono is quite a good photographer when he wants to be. He has two books published with photos of his. One was a very limited edition very expensive collection of photos that he took in Ethiopia called "A String of Pearls". There was also an art gallery showing of those photos in Dublin I think. Also the book "On the Move" which came out last year which had the text of his National Prayer Breakfast speech was illustrated with photos that he took except for the one or two that he was in where someone else used his camera to snap shots of him. But I do think in this instance he was just goofing around so maybe he didn't actually take any pictures. Just think of the story that photographer has to tell if Bono did actually take some of the shots and they were good enough to be used.
