Up until 2010, there were nearly no off-the-shelf cameras for consumers to create digital 3D photos and movies; it was pretty much a hobbyist or professional thing to do. But with people hungry for content to view on their 3D-enabled TVs or computers, manufacturers started trickling out cameras and camcorders this year that just about anyone can use for shooting 3D.
The cameras don’t all create 3D in the same way, though. Panasonic, for example, is currently relying on add-on lenses that feed stereo images to a single sensor. Fujifilm, DXG, and others, however, are using dual lenses and sensors, which is the more traditional way–and some might argue the best way–of creating stereoscopic images.
Sony skips both of these methods by using a single lens and high-speed shooting and processing to simultaneously capture left and right images that are stitched together in camera. (I expect the remaining manufacturers that don’t have 3D cameras to go this last route, as it’s likely the least expensive option to implement.)
Plus, there’s software to take the 2D content you already have and convert it to 3D, which saves you the trouble of buying a new camera or camcorder altogether. (You could always go back to film or DIY, too.)
