Luminance Slider For Color Correction Panel

[GoremanX]

Is it just me, or has the Luminance slider in the Color Correction panel become really lame compared to the same feature in Bibble 5? Seems like it has almost no effect anymore unless I move it to the extremes, and even then it's very subtle. It used to have drastic effect in Bibble 5 and was a very useful tool. Now it seems almost useless.

Very lame.

I haven't use this slider much, so I had to look at it.

To me, it looks like the Bibble 5 version is too heavy handed, and the AfterShot version is a little to subtle. If you like the way BIbble does it; maybe it's not the right tool for what you are trying to do? I ask this question because, for me, the AfterShot behaviour makes more sense. But stops a little short.

What do you mean "not right tool for what I want to do"? I've been using it for years, and it did what I needed... how is that not what I want?

It was a bit heavy-handed in Bibble, but at least it worked. I'd use it in small increments, 1 to 3% at a time. Usually anything more than 10% in any direction would be too much, though there were times I went farther than that. It also worked on more of the pixels. For example, adjusting the luminance slider for yellows also affected orange and green pixels in a predictable way because it adjusted the yellow component of those pixels.

In AfterShot, if I drop the slider by 50% in either direction, there is absolutely no visible effect to the picture. If I go to 100%, some of the selected colour's pixels get affected in a minimal way, but only the ones that are precisely that colour. The related ones are unaffected. Even increasing the Range slider doesn't help much. All I see is that some of the pixels of the selected colour become "grayer" It's pretty much pointless.
