This was taken about 10 minutes before sunrise and consisted of a set of 54 (18 sets of 3 bracketed [0, -2 & +2EV] exposures) vertical images at a relatively wide angle (35mm).
Each of the brackets were blended and then those results were then stitched into this very wide (probably around 250 degrees) panorama and a couple distracting elements were cloned out (lamp post, seat).
In this case it's hard to really see the image with this very small thin image and it's worth clicking through to the larger image to see more detail - and of course the 30,000 x 5,800 pixel master image looks great
