Noise Reduction Software

Do you own digital noise reduction software/plug-ins, or do you have a great technique for reducing/eliminating noise? Try them out on the attached photos (one with noise, one with texture) and post your results. Please explain what software/techniques you used.

Here's Kodak Digital GEM Pro, on the noise pic it is just the default settings, and on the texture pic it's maxed out (more as a demonstration than anything else, it can back the effect in a seemingly infinite variety of parameters, coarse/med/fine, dark/light, blending any of these or simply cranking them down). No additional processing of any kind was performed.

I ran the images through the Neat Image Demo program.

Noise image - ran default set-up.

Texture image - first one is with default, second version I changed the mode to remove all noise and adjusted the settings to bring back some detail.

I acquired this noise filter somewhere on my travels, not sure where. Ran the noise picture at standard setting, and the texture picture twice through on max setting.

I have both Neat Image Pro and Noise Ninja. I primarily (exclusively) use Neat Image. Maybe I'm just not understanding how to get the best out of Ninja.
For both Noise and Texture, I used my profiles for Nikon D100. For Noise I used 320 ISO setting and reduced sharpening to 45% in Y Cr Cb and conservative checked. The results are more contrasty than original.
For texture, I ran Neat Image twice at 1600 ISO With sharpening set at Y 45% Cr 40% Cb 35% conservative checked.

Cheers
Dave

I've done a gausian blurr with a radius 3 and then an unsharp mask radius 3.
Always works best for me.

I ran both pics through the psp 9 beta on board digital noise removal foto fix.
The little girl pic went ok but the pic got a little soft. I sharpened it up a bit with an extra layer , emboss and set to overlay.
With the textured pic a lot of the texture went away except some outspoken patches re : round his ear.

These were done by the new kid on the noise removal block. NoiseWare Community Edition. With the noise.jpg, I used the default setting. With the texture.jpg I put the removal at max. No other touch up.

I lost a program that removes this type of texture and I would really like to find it again. It had the choise of using different polygons at different sizes and power levels to blend out the texture. Please let me know if you see it.
