Path has released an update introducing Facebook support and new effects to its eponymous photo sharing app. In Path 1.5, users can now privately share their entire Path with specific friends on Facebook or publish individual Path moments on the Facebook Wall, with responses from friends rolled in with other Path activity displayed within the app. The update also introduces Lenses, a new feature that allows users to apply a variety of lens effects to photos and videos recorded within the app. The app includes four lens effects: Pro, Ansel, Instant and Diana with three additional effects available via in-app purchase for $1 each. Path is available from the App Store as a free download.
