Noise? What noise?

A screenshot showing a before and after noise reduction on a shot taken whilst in Shropshire.

The shot was taken at 1600 ISO, and is noisy. It's been brightened to show the ISO artifacts.

The after shot has been brightened by the same amount, but has had luminance and chroma noise adjusted too, using the Canon Digital Photo Professional. It's lost a little detail, but the effects are pretty good, I think.

What experience do you have with noise reduction software?

If I have the time I will do the same with CAMERA RAW 4. I can see lots of noise in the top shot but find that the bottom shot has lost a lot of detail in the grass and tree albeit with less noise. The sky looks good but has lost the colour too. So, is the colour in the top shot a result of chroma noise or a result of the reduction process?

I think I need to redo these, as I think the bottom one is darker, which changes the sky colour. Will re-post.
