TPAC2016 took place M-F in Lisbon, Portugal.

On Wednesday, 21 September, we held a "Plenary Day." As we did for TPAC2015, we organized most of the day as "camp-style" breakout sessions. We invited you to add to or comment on Breakout session ideas. The people at the meeting that day built the Session Grid, drawing from ideas socialized in advance and new ideas proposed the day of the meeting.

High Dynamic Range (HDR) on the Web

What is HDR

High-dynamic-range (HDR) is a technique used in video, imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard (SDR) video, digital imaging or photographic techniques.

What has changed since last year

  • CSS4 color with

* ICC support * CIE Lab * Working colorspace * Bit-depth neutral numbers

  • Convergence of Movie/TV, Digital Imaging, Web
  • ICC moving beyond print focus and D50 colorimetry

* ICCMax * spectral imaging * measurement conditions * viewing conditions * beyond paper white * compositing

  • Hardware support at volume

What do we need

  • HDR video on the web

* BT.2100 * PQ and log-gamma transfer function

  • HDR images (stills, photography)
  • CSS matching colors in the above
  • Compositing in linear-light colorspace
  • Compositing SDR with HDR
  • Fallback for SDR display

* Responsive images * Media Queries

  • HDR support in opensource codebases

* porting to TV does not add new major features

  • Developer awareness and guidance

* access to deep color, high bitdepth displays

  • Image format support for HDR

* freely implementable * HDR support (10bit PQ) * good compression * animation a plus

Next steps (two CGs)

  • Background explainer

* for the lightly yinterested developer * pointers to more information

  • Image format requirements

Next steps (liaisons)

  • W3C and ICC on Web profile of ICCMax
  • Continued review of CSS4 Color and CSS5 Color

Participants: Leonard Rosenthal (Adobe); Chris Needham (BBC); Mark Vickers (Comcast); Mike Assenti (Dolby); Stefan Håkansson (Ericsson); Lea Verou (Invited Expert, CSS); Frank Olivier (Microsoft); Mark Watson (Netflix); Chris Lilley (W3C); Liam Quin (W3C); Bert Bos (W3C); Florian Rivoal (Vivliostyle).
