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.
https://en.wikipedia.org/wiki/ColorChecker
The exposure meter in the camera does not know whether the subject itself is bright or not. It simply measures the amount of light that comes in, and makes a guess based on that. The camera will aim for 18% gray independently, meaning if you take a photo of an entirely white surface, and an entirely black surface you should get two identical images which both are gray (at least in theory). Thus enters the Macbeth chart.

Note that Chroma Key Green is reasonably close to an 18% gray reflectance.

Executing Python Scripts With a Shebang
https://realpython.com/python-shebang
In this tutorial, you’ll:
- Learn what a shebang is
- Decide when to include the shebang in Python scripts
- Define the shebang in a portable way across systems
- Pass arguments to the command defined in a shebang
- Know the shebang’s limitations and some of its alternatives
- Execute scripts through a custom interpreter written in Python
In short, a shebang is a special kind of comment that you may include in your source code to tell the operating system’s shell where to find the interpreter for the rest of the file:
#!/usr/bin/python3 print("Hello, World!")
