Noise Reduction

[Wineman]

I had to shoot at a high ISO yesterday and would like to reduce the noise. I do use Noiseware but have not mastered it yet (only got it yesterday) so does anyone have any PS tips?

I am guessing that George might have a trick up his sleeve ;)c

If you've PS CS2 the noise filter is qiuite good or dpownload the new NoiseNinja.

I use Neat Image and it works very well, making ISO 1600 useable. I read that Noise Ninja is as good but I have no experience with it.

Noise Ninja sounds like the way to go, I'm still stuck on PSP9...

I'm just used to it and an old fuddy duddy..

Noise Ninja is great.

I recently downloaded an action from the lights right studio at this linc.
http://www.thelightsrightstudio.com/ I have found it to be quite good

I just learned a really good noise reduction technique a few days ago from a newsletter that John Paul Caponigro sends out each month. I tried it and it worked beautifully for me. As a cave photographer, I expect a lot of noise in some of the long exposures I take if I use in-cave lighting. In fact, I'll be teaching this technique this summer at the cave photo workshop I'm leading at Carlsbad Caverns National Park. Here's how to do it:

Open your image and create a new layer from the original, giving you two layers of the same image. Change the blend mode to color. Working in the top layer, apply the Gaussian blur lightly until the noise disappears to your satisfaction (I used a radius setting of about 10). Flatten your image and the noise is gone. The reason this works so well is that you have done the Gaussian blurring in the color channel and preserved the sharpness of the image in the luminance channel where it resides. A lot of noise reduction filters tend to blur the image overall, but this technique seems to avoid that problem all together.

Attached are files of the original image, a blowup of a small section before and after noise reduction. You can still notice the faint white line in the fixed image, but the reddish color is clearly removed with no loss of image quality. Works for me!!
