I'll start things rolling with this:
A panorama across the Yarra River in Melbourne, Australia, taken just after sunset
last winter. 4 separate images stitched in Photoshop, with 30secs exposure time to
create the glassy reflections on the river surface.
Southbank on the left, with the 91-storey Eureka Tower (2nd tallest building in
southern hemisphere) dominating the skyline, and the CBD on the right, with the
historic Flinders St Station glowing in orange.
