How to reduce noise?

I am trying to figure out how to reduce the noise that is produced by using high ISO? I have both LR5 and PS6.

Thanks,

use the Noise Reduction slider in the Development Module.

It is MUCH more important to expose properly in the first place. If I get in right in camera, I have less work to do.

When in doubt, overexpose a bit. And when you sharpen, only sharpen the important bits - not the noise in the rest of the image.

Use Dropbox or another file host to provide a raw file you're having trouble with, and maybe some examples of results you're getting.

Try Noiseware http://www.imagenomic.​com/nw.aspx
I use it on my sports pics. Works well.

1. Expose properly (which may mean over expose slightly, then pull back exposure in post). Under exposure causes more noise.
2. Use Lightroom's Noise Reduction feature but use is sparingly. You will never get rid of all the noise. Trying to do so will result in lose of detail in the image. Zoom in to 1:1 on a key part of the image and adjust the slider slowly to see the balance between removing noise and removing/smoothing image detail.
3. Don't make a final judgement based on a 1:1 viewing. Zoom back out to view the image normally and you will see that a bit of noise will often not be noticeable.
4. If applying sharpening use the mask function to limit the sharpening to edges rather than small details as this will enhance the impression of noise.
5. If forced to shoot at extremely high ISO convert the image to B&W - people will think the noise is grain.
