I love seeing big panoramic shots of cities from above and this collection here of evening and night time shots has some crackers.
The Rio de Janeiro image brilliantly shows the jumbled nature of the terrain around which the city is built and however my favourite shot is probably that of Athens. Here the normally dominant Acropolis is dwarfed by the Saronic Gulf, and islands, in the background with the mountains of the Peloponnese in the far distance.
