Noir (iPhone/iPad): I downloaded this a while ago now and keep coming back to it. It can make some amazing and moody photographs out of the most ordinary and mundane (and even boring) shots.
“Noir Photo lets you transform your photos with beautiful, dramatic lighting and instant results.

The app does not support (yet?) upload to different social networks (as do other photograph-enhancing apps) but it will save a good quality image to your camera roll, and you can use other installed apps to upload to your preferred network, or share via email or SNS with friends and family.
