I don’t think the previous post showing a section of this magnificent building does it justice, so I used the Photoshop “merge” command to paste together 4 shots. Not entirely satisfactory either, as there are some weirdnesses in the stitching together, like the truck that passed by during the 4th shot.
The problem is with photographing buildings when you can’t get far enough back to get proper perspective. I used to solve this somewhat with a parallax distortion lens on my old Nikons, but iPhones have no such options.
Anyway, you get the idea (if imperfect) here.
The building, along with Gioto’s bell tower, is just staggering, as you can see, and this angle doesn’t even include Brunelleschi’s dome (at rear).
