There is an interesting new video photography app called, 8mm Vintage Camera by Nexvio, Inc., that brings your iPhone and iPod Touch back in time to capture the beauty and magic of old school vintage movies.
It accomplishes this by mixing and matching different films and lenses and it does a good job of it. The total number of combinations allow you to get a glimpse into retro filming with 25 old school looks from bygone eras. It even comes complete with retro colors, flickering video, light leaks, dust and scratches (my favorite), and frame jitters. You can add any of these to your video with a flick of your finger.
