  Camera arrays (CamArrays) are widely used in commercial filming projects for
achieving special visual effects such as bullet time effect, but are very
expensive to set up. We propose CamSwarm, a low-cost and lightweight
alternative to professional CamArrays for consumer applications. It allows the
construction of a collaborative photography platform from multiple mobile
devices anywhere and anytime, enabling new capturing and editing experiences
that a single camera cannot provide. Our system allows easy team formation;
uses real-time visualization and feedback to guide camera positioning; provides
a mechanism for synchronized capturing; and finally allows the user to
efficiently browse and edit the captured imagery. Our user study suggests that
CamSwarm is easy to use; the provided real-time guidance is helpful; and the
full system achieves high quality results promising for non-professional use.
