Is it noisy in here?

One of the things I have noticed is people trying to avoid using ISO above 200 like the plague, which is a good thing, right?
Well I'm probably one of very few guilty of cranking mine up to 3200.
Yep, that's right, not a typo here. Thirty two hundred. And I'll go higher when I have a camera that can.
Noise doesn't scare me. It probably should, but it doesn't. And don't get me wrong, I don't like it, and I don't like to have to remove noise in photoshop.  But what scares me more is having an underexposed picture that I have to lighten, which causes an uglier noise than just cranking up the ISO.
And I don't stop taking picture just because it's dark. (Yup, shot in the dark at night around a campfire before and got some amazing shots).
Another thing I have noticed is everyone feeling they cant do anything about their noise unless they purchase another expensive tool for removing that unwanted noise. Whether it be Noiseware, or Neat Image, or other plugins, people just settle for noisy pictures until they make that purchase.
Well I have recently discovered an awesome tool that I'm willing to bet more people have and don't even know about.
Maybe you have heard of Lightroom 3's new amazing noise reduction feature. I was jealous and mad that I just bought LR2 a few months ago. Bummed thinking I'm going to have to pay another 100 bucks to upgrade so that I can do quick noise reduction on a batch of photos.
But I've recently discovered that I have one of the most awesome noise reduction tools right in my own computer.
It's in my ACR. I'm not sure if all versions have it, as I've read that it's 6.0 or better (which must be what I have). But if you have ACR and 6.0 or better (is there a better yet? I'm no expert here) then try this. You may find yourself as estatic as I am.

Raw images work best
Open Image in ACR
(may want to zoom in 200% so you can see clearly how noisy it is and how the noise reduction it's working)

Click on Detail Icon (I think the third one over, looks like two triangles)

Start with color noise, slide color slider to zero, then slowly drag it to the right until the moment the color noise is gone. You'll see some noise, that is luminance noise. What your looking for is the red, blue and green color noise to turn gray

Then-

Drag the luminance slider to the right until visible noise disappears.

Be sure not to drag to far on either or you'll lose detail.

You can bump up the luminance detail slider if things get too soft, and bump up the luminance contrast to bring back detail if things start to look too flat.

You can then bump up the sharpening at the top to bring back sharpness and detail.

And for your visual pleasure... Pictures! ('Who doesn't love pictures?)

Enjoy your quiet pictures!
