Another picture of the Colmenar Viejo highway with the 4 Towers on the background. You can see the first one with a square frame at ‘The Veins Of Madrid: M-607 Highway’ . This last one was taken from the west extreme of the footbridge that crosses the motorway. In order to get the light trails in all the roads, I took 2 sets of 3 exposures: +2 EV, 0 EV and -2 EV. I generated 2 tonemapped images with each set, with the same parameters in Photomatix, and later, I mixed them with layers in Photoshop. I also applied manual digital blending with the exposures to correct the ghosting effects due to the trails and to get a more realistic look in the image.

Wow, I really like the light-trails in this shot. They almost look like lasers or small neon lights. The tall buildings in the background are pretty awesome as well. Lovely image!
