Go to filter, select noise then dust & scratches work from there.

Hi nanuv... Welcome to the forums.

There are two types of noise...
* Luminance
* Chroma (color)

If you're not sure which is causing you the most grief, upload (attach) a sample image so we can take a look. (See link below my sig if you need help with uploading an image.)

Re: noise removal in photoshop CS

Ya I know lot of programs and plugins remove the noise very well,
but I wanted to know the particular photoshop tricks with CS only.
Not with CS2 and CS3 where noise removal filter is present.

Re: noise removal in photoshop CS

So much of the noise you can see is from jpeg compression. If this came from the camera like this it may have been taken with a very low quality setting for jpeg. Blow it up as large as you can in photoshop and you can see whats causing the noise.

I used Neat Image with the filter preset for high frequency jpeg artifiact. Did a reasonably nice job. BTW - you have a very nice Black & White image.

I did a little Local Contrast sharpening and High-Pass filter sharpening in Photoshop
