Did you also walk around to the other side of the cupola to get a shot of the walls surrounding the vatican from that view? I was there about 4 years ago, and could've spent much more time there than I did.
Yup. I took that same shot when I was there. That trip is really what got me into photography. Quite the view from up there. I also had a shot just inside the cupola from almost the same angle as the Escher drawing. I was familiar with Escher before this trip but had never seen that print. I was later perusing some of his drawings and saw the sketch from inside the cupola and had an Aha moment and remembered taking the same shot as the drawing. I'd really like to go back now that I have an idea of how to take a decent picture.
