Now, don't laugh. This is a shot of my wife with a famous Canadian. (No, not Mike Meyers:-)) In the rush, I forgot that my lens adaptor blocks the flash. As you can see, the shot is severely underexposed. I can rescue almost all the detail, but have not had a lot of success with the colour noise. Here is a slightly smaller version of the original. Any tips would be greatly appreciated.

Here is a typical attempt of my own... Separate Luminosity, sharpen luminosity layer, blur colour layer, add levels, reduce red saturation.

I should mention... this was shot at Cancun Airport - the faces were a little sunburned. :-)

Did a levels adjustment and applied Noise Ninja. NN seemed to do a pretty good job. I didn't care for how red the skin tones were, so I desatured them a bit. I also added a bit of sharpening.

Nice job... and FAST too. :cool:That fella's shirt looks nice and white too. :-)

Question: did you do the noise reduction before or after the levels?

You're supposed to do it before, but I prefer to do it afterwards where I can see what I'm doing. If you apply it beforehand you might ruin some of the detail that you can't see, and then when you lighten it so that you can see it, it's already gone.

The nice thing about noise ninja is you can create a noise profile by sampling portions of the image, basically telling the program, "there's not supposed to be noise here." I sampled a chunk of the sign, his forehead, some of the clothing and a few spots in the background.

Thanks again, I'm really impressed. Ill have to try NN. I've been using Neat Image but it didn't clear up this shot.

Good result from Corpsy !

I too, use Noise Ninja. Wouldn't be without it ! Applied after first using Shadow/Highlights in CS2, then levels and contrast adjustments and lastly, a run through the High Pass filter for 'sharpening' purposes.

Amazing work, folks. I can hardly believe the amount of detail that you've been able to rescue in this image. My wife (a big fan of the former Prime Minister) is very impressed.

Thanks so much.
