This is Plaza Shopping, the biggest shopping mall in Niterói (lovely city just a few kilometers away from where I live. I even go to a university there!). I used my Nokia 6085 to take 21 pictures from the second floor and stitched them together with Hugin (I used autostitch first as a "preview", and then did it again on Hugin, which gives me more control over the process).
Should I get rid of the black empty espaces?
