Single-Camera and Single-Lens 3D Capture, from before the “Golden Age” to the future of 3D History and Possibilities…

It Began in the Golden Age… 1948: Dutch Veri-Vision system, “Queen Julianna” success begins Golden Age of 3D.  First prism/mirror single-camera system Spottiswoode brothers soon come out with superior 2-camera system. 2-cam rigs dominate Golden Age.

The Silver Age … …Was the Age of Single-Camera 3D 1966: Robert Bernier and SpaceVision  Over/under L/R images on one film strip for projection  Bernier realized same thing could be done in camera  Trioptiscope lens adaptor for over/under shooting on Mitchell camera Marks Polarized 3-Deepix etc. Condon and Silliphant: StereoVision and “The Stewardesses” Arrivision systems and “Friday the 13 th Part 3D,” “Jaws 3D” etc. Dimension 3 (Daniel Symmes) Digital Cyberscope (Douglas Trumbull) DOTS (Jimmy D. Songer Jr.) Single-Camera 3D was typical of ‘60s movies ethos: hand-holdable, independent production

Typical Light Paths

Typical Mirror/Prism Design

Problems with the Classic Designs… Keystoning Vignetting Sensor utilization Stray light bounces Repositioned focal length and focal distance of prime lens Light sensitivity Eyeballing alignment

Basic Advantages of Single Lens 3D No lens alignment issues Lighter weight, smaller package “Matched cameras & lenses” promises frequently broken Theoretically easier to rack focus, convergence, intraocular, integrate control of all with zoom “Silver Age” devices were used with film; shooting 3D on film would be nice

Some of the Problems Have Gone Away… C-mount lenses Tough design issues without optical design software Existing 3D rig infrastructure, general camera tech advances make for available standard components, precision controls And then there’s the new problem: lots of very different sensors.

Current Attempts Sony  Single lens followed by split light paths to 2 sensors  Specialized camera

Current Attempts ISee3D  Single camera and single lens  Shuttered alternating views for right and left  Specialized camera  Showed consumer prototype at CES

Current Attempts Loreo  2-lens attachment for consumer cameras  Over/under or side-by-side

Current Attempts Things we know we can achieve …  Single camera/single standard lens as preferred by DPs  Minimal light loss vs. 2D  Adjustable intraocular, convergence in concert with focus and zoom  Precise optics with unnoticeable keystoning, vignetting, stray light flares, misalignment  No polarizing effects  Minimal resolution loss vs. 2-sensor/camera systems  Use with film  Light weight, easy maneuverability  Output RT data in standard format for graphics, switching, multicamera integration.
