The fourth in the "ToyCamera" series of iPhone apps developed by Takayuki Fukatsu, QuadCamera uses the device's camera to create multiple images taken moments apart from each other. Similar to the normal iPhone camera, the user sees a single image on the screen, but QuadCamera takes a handful of shots spaced by adjustable time intervals. You can also choose between four and eight serial shots that can be oriented in a line or two parallel rows.
The effect is similar to that of Lomography cameras, only in digital form, but complete with soft focus and slightly overexposed edges. Like Lomography does for film, QuadCamera takes the inferior capabilities of the iPhone camera and adds creative tweaks to increase the fun quotient.
