Vibrance Versus Saturation

I posted an illustrated "tip" tonight that explains the difference between the new Photoshop CS4 Vibrance command and the familiar Saturation command.

Some people think Vibance and Saturation are the same. I used a test target from Bruce Lindbloom to demonstrate how Vibrance has more "smarts" than Saturation.

Thanks Mitch, I have a page up here too, which briefly goes into this - although more in pointing out that the command in ACR is not exactly the same as in Ps CS4:

I can link to your article if you like and would do the same.

Simple, Saturation is a linear correction, Vibrance (from Lightroom, originally purchased technology from a competing Raw converter), is non linear, making more saturated colors being affected differently then less saturated colors, with skin tone protection.

The differences between Vibrance in LR/ACR and Photoshop is one is gamma encoded, one is linear encoded so the code is going to be different (as well all similarly named commands).
