BlurXterminator Interview with Russel Crowman

MikeM

Hi Adam,

I really learned a lot from the interview video but had some questions on the Luminance only section.

1. Does Luminance option apply in OSC case?
2. In which case is this useful? I got the impression it was used where there was overcorrection to the non-stellar regions but not sure.
3. I assume this does not affect the color of the image?

1. Yes.

2. No... that isn't the use case. When BXT does its thing, it looks at the relationships between the channels and operates on them somewhat independently. If you use the Luminance option, it operates on a single image- the luminance component- and then blends it back to make a color picture. This will avoid some color weirdness in certain circumstances.

3. It does affect the color, but in a different way. It will not have the relationship between channel information- so chromatic aberrations will not be corrected for example. It will tend to not have dramatic color differences and may even dilute color in certain circumstances.
