For those wondering, the reason the power greater than 1 makes the rgb values smaller is because an important detail was left out- the rgb values here would not be on a range from 0 to 255, but 0 to 1, meaning for the most part the rgb value itself is number less than 1, so raising it to a power larger than 1 actually makes it smaller. For example, (1/2)^2 = 1/4, meanwhile, (1/4)^(1/2) = 1/2

You can check this effect out by comparing the graph "y=x" with everyone's favorite function from high school, "y=x^2". Most of the parabola will lie ABOVE the line y=x because squaring numbers greater than 1 makes them larger. But values between 0 and 1 have actually gotten smaller so the parabola dips below "y=x" in that region.

The other hint that this is happening is when he says "notice that the formula maps blacks to blacks and whites to whites" - notice that the only times the parabola intersects the line "y=x" is at zero and one. This is why mapping the rgb values on a scale from 0 to 1 makes so much more sense if you're going to make these color adjustments, because you can more easily preserve the color range as described here

Is this about the red pill and blue pill?

It needs to be noted that during production, they lit everything with green gels, and were very conscious about doing as much as possible in cam, there was no easy pessy color grading, it was pre digital intermediate.

I'm just happy to hear your voice, if I'm being honest. Been a long time fan of all of your articles, videos, and demos.

I want to make a game with different areas having different hues, I think this--adding a sort of shader that raises each value to a different power depending on the environment--might be a lot better a technique than trying to find a large yet limited feeling color palette

Oh no, it’s a linear transformation of an LCD inspired by the movie matrix! It’s the matrix matrix matrix!

Fun fact : the filter wasn't used in the theatrical release where there was no green tint it only came with the DVD version for marketing

[josephmathmusic]

I did fun versions of pictures of myself by applying such kind of formulas :)

Now I have to watch the movies again. I never notice lighting stuff

[KuraSourTakanHour]

I'm glad it was all shot in the matrix tint, the normal version has no charm

Enhorabuena por todo tu trabajo en todos estos años .. me tiene fascinado!! ...

[BLVGamingY]

rather, the freedom is preserved, the range isn't unless it's was max originally

[pedrosso]

So these channels are from 0 to 1, not 0 to 255?

[turdle]

well.. i have to go rewatch the matrix now. what a masterpiece. Thank you

[commanderpaladin]

I was thinking they are green because the movie is old

[smashman]

DVD green tint or original screening green tint

Sadly we can't precisly type in 7 / 8|5 in our curve

[herlantmajor]

Man I absolutely adore your shorts, I can’t wait to see more, this is computer graphics snacks for me

[aadik]

Wait how did a fraction greater than 1 took red and blue closer to zero?

Im just happy that the moment i saw the formula i understood what was going on... Im dumb... Understanding something with just looking, especially numerics related was a happy moment
