To take stereographs of dynamic subjects, we will need to take two photos at exactly the same time. Japanese camera manufacturer Fuji recently released the first digital camera equipped with two lenses for 3D. Of course, for the technologically savvy, you can make your own 3D camera rig using common building materials and two digital cameras. For this project, we’ll use a pair of matching Canon PowerShot cameras and specialized synchronization software called StereoData Maker, or SDM, which is a nonvolatile firmware upgrade based on CHDK, the Canon Hack Development Kit. SDM adds a set of features to certain Canon cameras, specifically for the taking of 3D pictures.
