After an ineffective search for Photoshop filters generating that vintage spirit on your own digital photos I ended up creating two different Photoshop droplets. First check the result from following photo:
Original photo

Photo using the "bd vintagefoto red" droplet

Photo using the "bd vintagefoto green" droplet

The two droplets are generating seperate layers containing your original photo, the photo with the colortint (red or green), a lens layer, a white rounded border and a black rounded border layer. The droplets are working with Adobe Photoshop CS3 (sorry, only CS3!) on Mac OSX or Windows. Just drag your JPG file(s) on one of the two droplets and wait for Photoshop doing his job.
(Files must be in RGB, not CMYK mode).
