3D - S3D - CG3D
The S in S3D is actually redundant because Stereo means ‘Solid’ i.e. 3D but it’s generally used to differentiate the computer generated 3D and the 3D achieved by shooting with two cameras or lenses. 

How it works
To produce 3D we shoot with two cameras plus 1 rig, or 1 camera with two lenses, the different points of view between the right eye and the left eye are used to recreate the depth. To do that, we shoot with two synchronized cameras, then we send the image from the left camera to the left eye, and the image from the right camera to the right eye. There are two crucial factors when shooting 3D: the interaxial, which is the distance between the centre of the lenses of the two cameras, and the convergence, which is the angle at which we position one camera with respect to the other one.

To hold and align the cameras, we use a 3D-Rig. There are two main types of 3D-rigs:
- The side-by-side rig, where the cameras are sitting, obviously, side by side. This kind of 3D-rig allows large interaxials, but not small interaxials (because of the physical size of the cameras). This is mostly useful for large landscape shots.
- The mirror rig, or beamsplitter rig. One camera films through a semi-transparent mirror, and the other films the reflection in the mirror. These rigs allow small and medium interaxials, useful for most shots.
Cameras must be accurately aligned, must have exactly the same brightness and color. They must be perfectly in sync, frame-wise and even scan-wise (an external sync box, plugged in to the Genlock inputs from the cameras, and is very often used to do just that).

How to watch 3D?
We have to use glasses for at least first generation 3D TV screens. The screens that don’t need glasses do exist -they’re called autostereoscopic screens- are still expensive and still have room for improvement. Having said that, look around you there are already a growing cadre of products, from TV screens to personal computers, cameras, telephones, video games, that use existing technology, which still works quite well for the moment.

Services
- Technical: We have access, through a whole international network of providers, to the latest cameras, rigs, screens, software, etc. to produce any type of film.
- Training: We’d like to share our knowledge and experience with genuine 3D visionary people. If you’d like to learn more about 3D from a technical point of view, we’ll cater for your specific needs such as training personnel, explaining and showing clients how it works.
- Consulting: If you have a project, a single idea or simply want to find out how 3D can benefit your business please call us to make an appointment. It makes sense ‘starting to think in 3D’.
We’ll help you to make it a real cost effective investment throughout the whole process of production.

Hundreds of millions are being spent on the technology and promotion of 3D in films, TV, telephones, games, tablets, etc.

- Marketing / Publicity
3D film offers companies the best way to display and promote their products and services. It’s the most realistic, sophisticated and high-touch way to reach discerning clients.
The result for viewers and potential clients: spectacular imagery, memorable experiences, and a value driver for sales.
