Oslo skyline (if it can be called that ), taken from the roof of the fabulous opera building.
Post-processing Lightened and turned up the recovery a bit and adjusted the wb in camera raw. Darkened with a black and white layer set to multiply (100%) with some of the buildings partly masked out. Turned up the contrast a bit with a black and white layer set to soft light (100%). Adjusted the different coulour channels with curves to give the picture a slightly warmer colour. Added some vignetting. Cropped to square, removed some noise and sharpened.
