Diptic, a photography app developed by Peak Systems, is currently available for free as the App Store App of the Week. The app has been designed to quickly and easily combine multiple photos to create a new collage. It offers over 52 frames to choose from and the user is able to tweak brightness, contrast and saturation, adjust border colour, width and curvature. Once created, the image can be saved or shared via email, Facebook, Twitter, Flickr, Tumblr or Posterous. Diptic will return to its normal price of $0.99 once the promotion ends on 19th July.
