This is a test showing the Vibrance sliders in Photoshop Camera Raw set to maximum, minimum, and mid point.
Please refer to this article here on PhotographWorks about the Vibrance versus Saturation sliders for the background to this test.
The final shot here is a superimposition of all three shots showing the effect side by side.

Another saturation tool is “Color intensity” in the “Match color” function. Often more useful to boost colors than Vibrance or Saturation.
I have never used the Color Intensity tool. I just tried it and it seems a useful tool.
Thanks for mentioning it.
I never knew this tool existed. Do you think it does something different to Vibrance? I can try it maybe, but good to see it here because you do tests I like to see.
“Color intensity” looks like an “intelligent” vibrance that would understand color visually rather than mathematically. It often works better than Vibrance and sometimes doesn’t work at all depending on the image. But since I tried Alien Skin Exposure I’m using these functions less and less, and prefer the various film emulations that plugin provides.
I just took a look at the Alien Skin video, but I don’t think it is for me. I didn’t see a ‘look’ that really blew my socks off, but that may be more to do with the fact that I am not finding time to shoot much of anything serious nowadays. Where are some of your images that I could maybe take a look at?
Haven’t posted images using Exposure yet. But what I’m after is not more colorful or more realistic images as such (I find visual reality pretty boring), but more cinematographic ones.
And for that one needs to somehow “damage” colors. Here’s an example of Exposure use for an advert by Anton Esteban.
