The Tinto 1884 lens uses facial recognition to recreate a very shallow depth of field unique for each photograph. This is similar in some ways to what some apps do with tilt-shift or radial blur effects, but Hipstamatic’s effect is more customized for faces. Notice, for instance, that it will leave eyes and mouth unaffected, while blurring out the nose and forehead.
Oh, this is clever. Via Rob Sheridan.
