Hi all,

I'm here again asking a strange question. :P

I would like to know the formulas that convert the R, G and B values to Luminance... what's the math behind that?

I would like to better understand what is represented in the histogram in terms of contributions given by the three components.

Pointing me to an online document that explains this math is also welcome.

Thanks.

P.S.: I hope this is not off-topic here.
