How does this feature work?

[Philip]

Instead of highjacking a recent thread about a "Fill light" filter I thought I would start a new thread and ask. I think GrassValley_KH posted the following in the fill light thread.

I'd use White Balance with the luminance limiter enabled - this will let you control say, highlights without affecting shadow, etc.

You will probably end up with more than one White Balance filter on the clip if you do it this way, but you'll have a great deal of control. And I like control... *grin*

I assume you are talking about the luminance "slider" controls in the middle of the white balance filter. I have never used these as I have no idea what they do. Can someone explain the function of the Luminance. A quickie tutorial from someone who really knows how to use these settings would be real handy. I know the White Balance is probably the most powerful tool in the Canopus Filter selection so I want to learn to really use it.

Evidentally there is lots more power in the filter than I initially thought.

Anybody know the functionality well enough to explain it a little. I really don't understand what the 4 little "handles" are for and the repercussions of their movement.

Thanks,

Actually that was me... but anyway... The limiters in the White Balance filter work the same way the limiters in the Chroma and Luminance Keyers work.
But most people never used those...

Essentially you have two boundary lines (or sliders) - the red line is the "hard" limit. Anything within this limit is completely affected by the key or effect.
The yellow line is the "transitional" limit. Anything between this line and the red line is partially affected (up to no effect just after the yellow line).

So you get a double-cross-hatch which is the "full" effect area. And a single-cross-hatch which is the "partial" effect area.

The easiest way to see how it works is to apply a heinous effect (like shift white to purple), enable the slider, and drag it along.

Thanks...between your explanation and the video tutorial someone posted me to I just learned a bunch today. You guys are smart.... :-)

The limiters are quite powerful, letting you "touch" only what you want to. Surgical strikes instead of all-out destruction. :)
