Excellent shot. Only suggestion I have is that with a bit more f-stop (it was obviously bright) and a slower shutter speed, using a tripod, you would have gotten the city in focus as well. That would have sharpened the picture and lifed it another level. But All round I'd say it's excellent and you have an excellent eye to have captured it.

This image really captures the depth-of-field thing very well. The seagull is in focus, and the city in the background creates the illusion that the bird is looking at the city. Beautiful.
Hey, lovely image, but is this shot taken from Alcatraz? It seems to be, but i thought that Alcatraz was more out of the coast of S.F... This seems so close to S.F
I love the photo too, only would be great to see the seagul's whole tail. Sorry, I know it must have been not easy to capture such a view, but still this would do the picture ideal. And it was a great idea to sharpen only the bird and make the city fade - SUPER.
