I took this photo in Albany, NY. Not only was it colorized from it's original b&w but there were also elements added to give it an ethereal sci-fi look. Those elements are lens flare from Photo shop filters, a half earth file borrowed from an on-line source. And mysterious disembodied orbs, following the lines of the auto headlights (traced by a 10 second time exposure in the original negative).

Have fun, get out your old negatives and bring them to life again. You can scan old photos by using a flat-bed scanner or if you've got a ton of old negatives you can purchase an inexpensive film scanner. I paid about $250 for a Minolta-Konica film scanner. It works great!
