Re: Converting Primaries


Troy Sobotka <troy.s...@...>
 

Convert the xy coordinates to XYZ, with red being the first column, then green, then blue. That forms a 3x3 matrix for taking linearized RGB to the XYZ domain.

From there you would need to perform a chromatic adaptation via Bradford or CAT02 to the AP1 or AP0 white point required.

The final matrix would be from XYZ, achromatic point aligned, to AP1 or AP0 RGB, which are well documented.

With respect,

Hello,

I just wanted to know if you would be able to help me convert these primaries into the proper matrix for use with ACES? They would be for an input. 

r: 0.6484 0.3309

g: 0.2302 0.7016

b: 0.1559 0.0661

w: 0.3217 0.3291

Thank You
