Virtual Production Offers Real Savings For Studios Of All Sizes
Rob Legato, the award-winning FFX Supervisor whose work you may have seen in movies like Titanic, Avatar and The Jungle Book, is incredibly bullish on virtual production. At the Microsoft Production Summit, presented by NVIDIA NVDA +0.2%& Unreal Engine in Los Angeles, he reported that he recently did a movie with Ben Affleck and Matt Damon in twenty-four days, “Cutting down the days cut down the budget, and it’s amazing what a difference that can make. Productions can now do for $25 million what used to cost $100 million.”

PBR Color Reference List for Materials – by Grzegorz Baran
“The list should be helpful for every material artist who work on PBR materials as it contains over 200 color values measured with PCE-RGB2 1002 Color Spectrometer device and presented in linear and sRGB (2.2) gamma space.
All color values, HUE and Saturation in this list come from measurements taken with PCE-RGB2 1002 Color Spectrometer device and are presented in linear and sRGB (2.2) gamma space (more info at the end of this video) I calculated Relative Luminance and Luminance values based on captured color using my own equation which takes color based luminance perception into consideration. Bare in mind that there is no ‘one’ color per substance as nothing in nature is even 100% uniform and any value in +/-10% range from these should be considered as correct one. Therefore this list should be always considered as a color reference for material’s albedos, not ulitimate and absolute truth.“

Nick Saraev – How AI Will Completely Dominate the Animation Industry In Less Than 5 Years
https://nicksaraev.com/ai-animation-is-coming/
“If you’re looking to get into animation as a career, you have less than five years.
Why?
- DALL-E 2 and other AI art models can now produce a near-infinite variety of illustrations using a simple text prompt. By 2025, they’ll outperform human artists on every metric.
- AI animation models already exist that can take a static illustration and “imagine” different movements, poses, and frames. You can make the Mona Lisa smile, laugh, or cry – and there’s nothing stopping you from doing that to other images, too.
- AI video models are right around the corner. Soon, studios will be able to create smooth videos of any framerate with nothing more than a text prompt. Short films will be next.

Unity – HDRI processing
The goal is to clean the initial individual brackets before or at merging time as much as possible.
This means:- keeping original shooting metadata
- de-fringing
- removing aberration (through camera lens data or automatically)
- at 32 bit
- in ACEScg (or ACES) wherever possible

Open source Cycles render implemented into Gaffer
https://github.com/GafferHQ/gaffer/releases/tag/1.0.3.0
https://github.com/GafferHQ/gaffer/pull/4812
This release introduces support for the open source Cycles renderer. This is introduced as an opt-in feature preview intended for early testing and feedback as breaking changes can be expected while we continue to improve Cycles integration in future releases. As such, the use of Cycles is disabled by default but can be enabled via an environment variable. Additionally we’ve added support for viewing parameter history in the Light Editor, automatic render-time translation of UsdPreviewSurface shaders and UsdLuxLights for Arnold and made the usual small fixes and improvements.

StudioBinder.com – Photography basics: What is Dynamic Range in Photography
https://www.studiobinder.com/blog/what-is-dynamic-range-photography/
https://www.hdrsoft.com/resources/dri.html#bit-depth
The dynamic range is a ratio between the maximum and minimum values of a physical measurement. Its definition depends on what the dynamic range refers to.
For a scene: Dynamic range is the ratio between the brightest and darkest parts of the scene.
For a camera: Dynamic range is the ratio of saturation to noise. More specifically, the ratio of the intensity that just saturates the camera to the intensity that just lifts the camera response one standard deviation above camera noise.
For a display: Dynamic range is the ratio between the maximum and minimum intensities emitted from the screen.
