Quad Camera - app.
This app takes the iPhone camera, and shoots in panels to create an almost ‘photobooth’ effect. You can adjust the timer between snaps, and the layout can be 2x2, 4x1, 4x2, and 8x1. The color setting can be vivid, dull, grayscale, bright, hi-con, and no effect.
Overall I rate this a 4.5/5
The above image was shot in vivid mode, with a 2x2 layout. The timer was 1.7.
