Taken from my recent trip to Sydney from our room at the Hilton, Sydney. 5 Shot HDR quickly mashed together so its not perfect by any means, but still pretty
Not really much done to it - Set some minor Lens Correction (I cheat and use the Pentax FE Profile that seems to work ok on this lens as well) and Embedded Colours, fused the 5 images in Photomatix, then Tonemapped them fairly lightly.
In retrospect posting it - I probably should have taken 30 more seconds to dodge the front buildings a little (just a smidge) to make it match the scene as I took it, but its pretty darn close...
