How does cyclesThere are many ways to calculate RGB to BW. Which of those ways does Cycles use in the conversionRGB to BW node? I've read (I took a quick look at the manualgit repository, but it's not searchable and I know what it does but I'd like to know how it does itcouldn't find the node source code.)
Clarified that the question is specific to cycles and not a general question about color space transforms
