and what i did...
lets see, i lightened it with curves, i lowered the saturation and added a sepia-ish tone, i used a whole bunch of different filters on a bunch of layers all at only partial opacity (including torn edges, glowing edges, lens correction (for vignetting) um... i don't remember the others) and used a few brushes to add some darkish lines... i think thats it, but i was just messing around for a bit, might've forgotten something :P
