Walt Disney Pictures VFX Workers Move to Unionize
https://variety.com/2023/artisans/news/walt-disney-pictures-vfx-workers-union-1235706136/
A supermajority (over 80%) of the 18 in-house VFX crew members at Walt Disney Pictures signed authorization cards signaling their desire to unionize.
The historical move is the second time in history that VFX professionals have joined together to demand the same protections and rights as their colleagues. Earlier this month, VFX crews at Marvel Studios voted to unionize beginning Aug. 21. Ballots are due on Sept. 11, and the vote count will take place on Sept. 12.

GretagMacbeth Color Checker Numeric Values and Middle Gray
The human eye perceives half scene brightness not as the linear 50% of the present energy (linear nature values) but as 18% of the overall brightness. We are biased to perceive more information in the dark and contrast areas. A Macbeth chart helps with calibrating back into a photographic capture into this “human perspective” of the world.
https://en.wikipedia.org/wiki/Middle_gray
In photography, painting, and other visual arts, middle gray or middle grey is a tone that is perceptually about halfway between black and white on a lightness scale in photography and printing, it is typically defined as 18% reflectance in visible light
Light meters, cameras, and pictures are often calibrated using an 18% gray card[4][5][6] or a color reference card such as a ColorChecker. On the assumption that 18% is similar to the average reflectance of a scene, a grey card can be used to estimate the required exposure of the film.

OpenAI may go bankrupt by 2024, AI bot costs company $700,000 every day
While OpenAI and ChatGPT opened up to a wild start and had a record-breaking number of sign-ups in its initial days, it has steadily seen its user base decline over the last couple of months. According to SimilarWeb, July 2023 saw its user base drop by 12 per cent compared to June – it went from 1.7 billion users to 1.5 billion users.

WGA Response to Studios Indicates No Quick End to Strike
https://variety.com/2023/biz/news/wga-response-studios-not-quick-strike-1235697413/
The two sides remain at odds on items across the board, including streaming residuals and a higher minimum tier for TV writer-producers
The WGA wants to tie streaming residuals to the popularity of a show, but streamers had adamantly refused to share such viewership data.
The WGA is also seeking a provision that would allow its members to honor other unions’ picket lines.

Most bosses regret how they mandated workers return to the office. They blamed it on not having enough data
Four in five (80%) of bosses told workplace software firm Envoy that, had they had a better grasp on actual employee preferences, they would have taken a starkly different approach to their return to office plans. The problem, they said: They didn’t have access to workplace data to help them make their decision.

Unpremult and Premult in compositing cycles

The simple definition of premult is to multiply the alpha and the RGB of the input together.
Un-Premult suggests that this does the opposite operation to the premult node. Therefore instead of multiplying the RGB values by the alpha, it divides instead.
Alan Martinez
“Unpremult” and “premult” are terms used in digital compositing that are relevant for both those working with computer-generated graphics (CG) and those working with live-action plates.
“Unpremult” is short for “unpremultiply” and refers to the action of undoing the multiplication of a pixel by its alpha value. It is commonly used to avoid halos or unwanted edges when combining images. (This by making sure that edits to a layer are added independently from edges’ opacity levels.)
“Premult” is short for “premultiply” and is the opposite process of “unpremult.” In this case, each pixel in an image is multiplied by its alpha value.
In simple terms, premult crops the RGB by its alpha, while unpremult does the opposite.It’s important to perform color corrections on CG renders in a sort of sandwich approach. First, divide the image to extend the edges fully of the RGB channels. Then, apply the necessary color corrections. Finally, pre-multiply the image again to avoid artifacts on the edges.
Typically, most 3D rendered images are premultiplied. As a rule of thumb, if the background is black or even just very dark, the image may be premultiplied. Additionally, most of the time, the 3D render has antialiasing in the edges.
