Yes, in fact, I built a reference profile a long time ago by filming a color test card with colored & gray squares. And I use that as my fixed reference to set noise level sliders for everything I shoot. I have one for standard definition and one for high definition. My point I was trying to mak...

In my work as a film maker, I set the noise levels up to the point where image details start to be affected. For luma, I watch texture in skin, carpet, fabric or wood grain, etc. For chroma, I check to make sure that color changes are not bleading across edges. For both luma & chroma, I then bac...

YCrCb Symmetric

Greetings. What is the "YCrCb Symmetric" colorspace? The user guide has recommendations about its use, but I couldn't find any definition of it. As an Indy-film maker who works a lot with color, I'd personally appreciate an actual definition, such as "Y is equal weight of R, B and G&q...
