Set Visit: 3D Short Film

 I was recently invited to a set of a short French film shooting in Stereo 3D. Since we often hear about big 3D movies, I thought I’d offer my photos of a low-budget 3D production.

The film was La troisième voie (The Third Way) a cop story with a twist directed by Jean-Michel Tari, with cinematography by Paul-Anthony Mille and stereography by Cédric-Alexandre Saudinos.

The 3D short was shot with a P+S Technik Freestyle Rig & Silicon Imaging SI-2K cameras connected to a 1 Beyond Wrangler Mini3D box recording Cineform RAW Quicktime.


The location: a warehouse complex outside Paris.

The film was mostly shot with 14mm Zeiss Digiprimes. The SI-2K camera, the black box with the orange band, really is tiny.


The L-shaped Freestyle rig is connected to a matte box assembly containing a half-silvered mirror that provides the same image to the horizontal and vertical cameras.


The Height knob is one of several used to align the 2 cameras, so that their 2 images overlap precisely.

The rig on an Atlas head. Here the follow-focus knob is used to adjust the IA (inter-axial distance) during the shot. The IA is the horizontal offset between the images from the 2 cameras. It is analogous to the distance between our 2 eyes.


The signals from the two SI-2K cameras were fed into a 1 Beyond Wrangler Mini3D recorder/monitor box (upper right), with recording done in the Cineform RAW Quicktime format.

The director and crew were able to previsualize the 3D effect by monitoring an anaglyph output of the Wrangler that required red-blue glasses.


Stereographer Cédric-Alexandre Saudinos explained that they chose to shoot with converging cameras (as opposed to parallel). They also changed the inter-axial distance as required by movement of the actors or the camera.
He added that shooting converged introduces some keystoning in the image, which may require correction in post.
Shooting parallel has no such keystoning problem, but does require cropping the edges of the image to allow for convergence in post (shooting converged doesn’t).


Director Jean-Michel Tari speaks softly… but carries a big stick


In between set-ups…


The HMI lighting package for the day exterior consisted of a K5600 Alpha 4K, a 12K (not shown) and a 2.5/4K with a Chimera. This was supplemented with some Kino Flo fill.


The valiant actor Stéphane Metzger is strapped into a custom Snorricam by Stéphane Jegou. The SnorriCam is a device that attaches the camera to the actor to obtain a distinctive viewpoint: the actor is stationary in the frame while everything else moves.
