Double Negative use Spheron HDR Cameras in latest VFX Production – JOHN CARTER

Spheron-VR AG, known globally as pioneers in HDR (High Dynamic Range) capture device technology and experts in precision engineered equipment & imaging optics, are today pleased to reveal that its customer Double Negative, the award-winning visual effects and animation company, have successfully utilized the Spheron HDR Camera technology in their latest VFX production, for the film John Carter.


This latest Disney production – John Carter (due for release March 9th)  is a film directed by Academy Award® winning filmmaker Andrew Stanton. Based on a classic novel by Edgar Rice Burroughs, it’s a sci-fi action-adventure set on the mysterious planet of Barsoom (Mars).

Both Ryan Cook & Ken McGaugh, Double Negative’s VFX Supervisors explain how the SpheroCam HDR was a powerful addition to their production resources in the making of this movie – ‘the cameras ability to automatically capture lighting environments and to record 3D data whilst onset was exceptional.’

‘It addresses many onsite FX data gathering issues that had previously slowed down productions. The time it takes to survey sets and locations as well as shoot reference lighting data is always an imposition on the live-action crew as well a less precise practice. By using our Spheron Camera’s this process became a much more efficient and a more accurate all-round solution. Two Spheron Camera units were used extensively on film locations around the globe, including in various London UK based Film Studios, as well as onset on locations such as, in the arid sandy Deserts of Utah in the USA. In all, over 2000 HDR images were captured for use in the production of John Carter’ explains Ryan Cook.

The SpheroCam HDR is able to capture 360º spherical images in a single scan. With 26 f stops of exposure and clarity of up to 50 mega-pixels, the SpheroCam HDR provides the optimum image quality for 3D image rendering. The camera is also excellent at recording spatial data, using its 3D immersive measurement technology; it enables CG objects to be placed into any location - bridging the gap between the real world and computer graphics environments.

Ken McGaugh said ‘Onset we captured both HDR light fields as well as making use of the cameras photogrammetric technology. This Photogrammetry element, which also records 3D points, has now been adapted into Double Negatives workflow, by the in-house development of a unique 3D photogrammetric pipeline, using both the 32-bit image data and measurement features, so assisting further in the Virtual Set re-Construction process.'
