Method and apparatus for multiple camera alignment and use

A method for aligning camera modules in a camera rig system for 3D stereo photography, the system comprising at least two fixed camera modules and a movable mirror assembly, the method comprising:

• mounting a first camera module in a horizontal orientation and a second camera module in a vertical orientation onto respective camera mounts;
• rotating the mirror assembly around a first rotational axis;
• and
• moving the mirror assembly along at least one of a first optical axis of the first camera module and a second optical axis of the second camera module, such that the incoming light transmitting through the mirror assembly toward the first camera module and the incoming light reflecting from the mirror assembly toward the second camera module are coincident at a reflective surface of the mirror assembly,
• wherein the first optical axis, the second optical axis, and the first rotational axis are perpendicular to each other, the mirror assembly is angled at roughly 45 degrees from the first optical axis or the second optical axis.
