shit i used to have a ton of wicked nice chris o connell pics, but if u go to his website ( www.chrisoconnell.com ) (sp?) look at the one of david chrichton with the red sky, or the one of t hall on the quarter pipe
what i did was took a really long exposure of lights ( i took about 6 of these pics.) then i developed them. then i scanned them into photoshop and layered them on top of each other, added some blue and a filter on the background image.
