I'm currently trying to learn some basics about various aspects of color grading. As such, I have a few questions/statements I'm hoping some of you can help me with answering/confirming
- 1 pixel contains the color channels Red, Green and Blue. - correct?
- Each color channel in 1 pixel carries its own luma value (how bright or dark each color can become). And the luma value for each color channel in 1 pixel is between 0-255. If the luma value for each color channel in 1 pixel is 255 it will reduce white. - correct?
- When talking about the bits of an image, you're talking about the bits per channel in 1 pixel. So this means e.g. 8 bits for the Red, Green & Blue channel. This also means that there are 256 different values/shades of color per channel - correct?
- A 10-bit image will be able to reproduce more shades of color. E.g. in terms of gradient. And working with 10-bit footage means more color information to use for grading. - correct?
- 4:4:4 stands for 4 pixels cross and another 4 pixels across below. - correct?
- 4:4:4 is great for green screen as each pixel carries it's own chroma value. - correct?
I hope you guys can help
