Tonight, I wanted to combine this great building with elements of movement, so went for four seperate exposure for the traffic light trails.



The hardest part was trying to get the white balance right as there is a mixture of light sources from sodium street lighting to the bright white flourescent lighting on the building.

I combined the layers using "lighten" blend mode and then burnt he sky back towards black to get rid of some lens flare that came a light to the upper right off frame.

All four shots were at 100iso, 20 second exposures at f13 in AV mode.
