Rio de Janeiro
As seen from Pão de Açúcar (Sugarloaf Mountain). Copacabana beach on the far left all the way to the Santos Dumont Airport on the right. Cristo Redentor is in the top middle-left far in the background, the white statue on the highest peak - barely visible here, but it's there.
Panorama made from 10 separate photos since I only had my travel pancake lens, which took a long time to process, but on the bright side, I have over 65 million pixels to play with.
