3D HDR (HIGH DYNAMIC RANGE) IS COMING

What is 3D-HDR ?

Traditional imaging techniques are incapable of capturing accurately or displaying the wide range of lighting in the real world. Some areas may be under-exposed and others over-exposed. High Dynamic Range (HDR) imaging technologies are an exception: HDR can capture and deliver a wider range of real-world lighting to provide a significantly enhanced viewing experience.

3D Stereoscopy,  on the other hand, is an imaging technique which enables or improves the illusion of depth by presenting two offset images to each of the viewer’s eyes. It has been shown to provide a strong cue for distance judgements and is capable of improving task performance.

3D-HDR, also known as Stereoscopic High Dynamic Range (SHDR), has the potential of bringing these diverse technologies together, exploiting the advantages of both. This novel imaging method with an unprecedented level of realism has the potential to deliver both improved depth perception and a realistic representation of the scene lighting.

Who is doing 3D-HDR?

3D-HDR is a pioneer field explored by only a few companies. GOHDR (UK) will present its first 3D-HDR solutions at the NAB in April 2012.  …

VIEWSONIC SURPRISES WITH 3D

…  Now Viewsonic has already displayed the ability to create a polarized 3D monitor and the new model, the V3D271 which will be on sales soon, provides for more widescreen “real-estate” for 3D, being a 27-inch widescreen. It also adds more powerful built-in stereo speakers for audio use (dual 2-watt amplification).  The choice of polarization for 3D makes perfect sense with a monitor: besides the simple fact that the 3D glasses are lightweight, compared to “active” glasses which require electronics and batteries in order to function, the polarized screen of a display is easier on the eyes as well. For sure there is a resolution issue (polarized being less than that of “active”), but on the plus side the image is brighter, the viewing angle less problematic for the viewer and the end price less than if the 3D was created using “active” technology.  All these factors contribute to making a polarized 3D screen an attractive proposition for a monitor.

But ViewSonic is also touting a new TV line  which doesn’t have 3D built in. Now I can understand excluding Internet capabilities, but for a company like Viewsonic who knows what they are doing when making a monitor, not offering 3D seems a bit off-putting. …

Specification for Naming VFX Image Sequences Released

ETC’s VFX Working Group has published a specification for best practices naming image sequences such as plates and comps. File naming is an essential tool for organizing the multitude of frames that are inputs and outputs from the VFX process. Prior to the publication of this specification, each organization had its own naming scheme, requiring custom processes for each partner, which often resulted in confusion and miscommunication.

The new ETC@USC specification focuses primarily on sequences of individual images. The initial use case was VFX plates, typically delivered as OpenEXR or DPX files. However, the team soon realized that the same naming conventions can apply to virtually any image sequence. Consequently, the specification was written to handle a wide array of assets and use cases.

To ensure all requirements are represented, the working group included over 2 dozen participants representing studios, VFX houses, tool creators, creatives and others.  The ETC@USC also worked closely with MovieLabs to ensure that the specification could be integrated as part of their 2030 Vision.

A key design criteria for this specification is compatibility with existing practices.  Chair of the VFX working group, Horst Sarubin of Universal Pictures, said: “Our studio is committed to being at the forefront of designing best industry practices to modernize and simplify workflows, and we believe this white paper succeeded in building a new foundation for tools to transfer files in the most efficient manner.”

This specification is compatible with other initiatives such as the Visual Effects Society (VES) Transfer Specifications. “We wanted to make it as seamless as possible for everyone to adopt this specification,” said working group co-chair and ETC@USC’s Erik Weaver. “To ensure all perspectives were represented we created a team of industry experts familiar with the handling of these materials and collaborated with a number of industry groups.”

“Collaboration between MovieLabs and important industry groups like the ETC is critical to implementing the 2030 Vision,” said Craig Seidel, SVP of MovieLabs. “This specification is a key step in defining the foundations for better software-defined workflows. We look forward to continued partnership with the ETC on implementing other critical elements of the 2030 Vision.”

The specification is available online for anyone to use.
