Candela
Candela is the basic unit of measure of the entire volume of light intensity from any point in a single direction from a light source. Note the detail: it measures the total volume of light within a certain beam angle and direction.
While the luminance of starlight is around 0.001 cd/m2, that of a sunlit scene is around 100,000 cd/m2, which is a hundred millions times higher. The luminance of the sun itself is approximately 1,000,000,000 cd/m2.NIT
https://en.wikipedia.org/wiki/Candela_per_square_metre
The candela per square metre (symbol: cd/m2) is the unit of luminance in the International System of Units (SI). The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m2).[1] The term nit is believed to come from the Latin word nitēre, “to shine”. As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device.
NIT and cd/m2 (candela power) represent the same thing and can be used interchangeably. One nit is equivalent to one candela per square meter, where the candela is the amount of light which has been emitted by a common tallow candle, but NIT is not part of the International System of Units (abbreviated SI, from Systeme International, in French).
It’s easiest to think of a TV as emitting light directly, in much the same way as the Sun does. Nits are simply the measurement of the level of light (luminance) in a given area which the emitting source sends to your eyes or a camera sensor.
The Nit can be considered a unit of visible-light intensity which is often used to specify the brightness level of an LCD.
1 Nit is approximately equal to 3.426 Lumens. To work out a comparable number of Nits to Lumens, you need to multiply the number of Nits by 3.426. If you know the number of Lumens, and wish to know the Nits, simply divide the number of Lumens by 3.426.
Most consumer desktop LCDs have Nits of 200 to 300, the average TV most likely has an output capability of between 100 and 200 Nits, and an HDR TV ranges from 400 to 1,500 Nits.
Virtual Production sets currently sport around 6000 NIT ceiling and 1000 NIT wall panels.The ambient brightness of a sunny day with clear blue skies is between 7000-10,000 nits (between 3000-7000 nits for overcast skies and indirect sunlight).
A bright sunny day can have specular highlights that reach over 100,000 nits. Direct sunlight is around 1,600,000,000 nits.
10,000 nits is also the typical brightness of a fluorescent tube – bright, but not painful to look at.

Tests showed that a “black level” of 0.005 nits (cd/m²) satisfied the vast majority of viewers. While 0.005 nits is very close to true black, Griffis says Dolby can go down to a black of 0.0001 nits, even though there is no need or ability for displays to get that dark today.
How bright is white? Dolby says the range of 0.005 nits – 10,000 nits satisfied 84% of the viewers in their viewing tests.
The brightest consumer HDR displays today are about 1,500 nits. Professional displays where HDR content is color-graded can achieve up to 4,000 nits peak brightness.High brightness that would be in danger of damaging the eye would be in the neighborhood of 250,000 nits.
Lumens
Lumen is a measure of how much light is emitted (luminance, luminous flux) by an object. It indicates the total potential amount of light from a light source that is visible to the human eye.
Lumen is commonly used in the context of light bulbs or video-projectors as a metric for their brightness power.Lumen is used to describe light output, and about video projectors, it is commonly referred to as ANSI Lumens. Simply put, lumens is how to find out how bright a LED display is. The higher the lumens, the brighter to display!
Technically speaking, a Lumen is the SI unit of luminous flux, which is equal to the amount of light which is emitted per second in a unit solid angle of one steradian from a uniform source of one-candela intensity radiating in all directions.
LUX
Lux (lx) or often Illuminance, is a photometric unit along a given area, which takes in account the sensitivity of human eye to different wavelenghts. It is the measure of light at a specific distance within a specific area at that distance. Often used to measure the incidental sun’s intensity.

Clint Eastwood on the set of his latest movie
Read more: Clint Eastwood on the set of his latest movieAt the age of 94, this is what the great Clint Eastwood looks like.
Standing, lucid, brilliant, directing his latest film. Eastwood himself says it: “I don’t let the old man in. I keep myself busy. You have to stay active, alive, happy, strong, capable. I don’t let in the old critic, hostile, envious, gossiping, full of rage and complaints, of lack of courage, which denies to itself that old age can be creative, decisive, full of light and projection. Getting older is not for sissies.”

Why VFX workers are unionising in Hollywood — and why it’s important
Read more: Why VFX workers are unionising in Hollywood — and why it’s importanthttps://www.digitalspy.com/movies/a44936059/vfx-workers-unionising-hollywood/
Last March, IATSE released a damning survey that showed how visual effects workers lack access to essential benefits, such as health insurance and retirement plans.
It also found VFX crews are lacking breaks and rest periods, and they’re not getting paid for working overtime, resulting in some workers failing to even make minimum wage.
This survey was aimed to organise VFX workers, one of the last areas of the production community that are still not unionised. Given the worsening of their working conditions while their craft is increasingly in demand within the industry, seeking protection has become a necessity.

Why every game developer is mad with Unity right now, explained
Read more: Why every game developer is mad with Unity right now, explainedhttps://www.gamesindustry.biz/unitys-self-combustion-engine-this-week-in-business
$1.3 billion – Unity’s lifetime accumulated deficit as of December 31, 2021. Unity has never had a profitable quarter in its history. It has posted modest operating profits in the past three quarters for the first time ever,
Unity lit money on fire for decades to buy a market advantage that overrules the basic economic incentives that supposedly ensure free markets work best for customers. It was successful in doing that because it’s very hard for a sustainable business to compete against one that is fine losing billions of dollars.
First, you make yourself essential to the market, even if it costs you billions to get there. Then once you hit a threshold – let’s say, I don’t know, 70% of the market – you lean into the enshittification process. You charge more for your services, you give your customers worse terms, you turn the heat up slowly and continuously, confident in the knowledge that people are so locked in to your business and have so few viable alternatives that they may grumble but they will ultimately put up with it.
And it’s such a common strategy in so many industries today that there’s just no sense of horror or outrage from the onlookers. Industry watchers and Serious Business People have seen this play out so many times they just acknowledge it’s happening and treat it as if it’s a perfectly cool and normal thing and not illegal predatory pricing.
I think this new Runtime Fee makes perfect sense from a mile-high point of view, if you think about Unity as a business where you just turn whichever dials and pull whatever levers will make the numbers go up the most.
The only problem is it makes no sense at all if you instead think about Unity as a game development tool that game developers should want to use.

“The uproar is primarily driven by two factors: Unity is attaching a flat per-install fees to games that use its engine, and it’s arbitrarily scrapping existing deals and making the changes retroactive.
The policy announced yesterday will see a “Runtime Fee” charged to games that surpass certain installation and revenue thresholds. For Unity Personal, the free engine that many beginning and small indie developers use, those thresholds are $200,000 earned over the previous 12 months, and 200,000 installs; one those marks are met, developers will be charged 20 cents every time someone installs their game.
Another big issue is that Unity has made this change retroactive: It supersedes any existing agreements with Unity that developers may have made, and it applies to games that were released even before any of this happened. The revenue threshold will be based on sales after January 1, 2024, when the new pricing system takes effect, but sales that occurred before that date will count toward the install threshold.
