This is a shot I took of the Putrajaya mosque. Just before sunset. Taken with the Canon EOS 5D and 35mm L mounted on a tripod with an ND graduated filter. Processing done in Apple Aperture. BW conversion in PS Elements with dodging and burning.
The tones in the image blows me away all the time and I was quite fortunate to have had the graduated filter on the 35mm as it really brought out the details on the clouds without sacrificing the exposure.
