As the lights turned green they shot off but had to slow down to crawl 50 yards later as the crept round the corner into Regent Street. This is 3 exposures with -1+ stops bracketing, then Photomatix for HDR and tonemapping, and finally Photoshop for the finishing touches including selective colouring.
