Anything like this that gets you thinking is good as no "right" way of course.

Thanks, Rob.
I think I first saw an example of noise reduction of linear data in a post by Juan introducing noise reduction using ATWT. It seems intuitively, to me at least, a good idea to tackle noise early and it does allow you to start with a slightly more aggressive stretch.
I use a clipped luminance mask to protect the bright areas and normally prefer ATWT or MMT with noise reduction only at the smallest wavelet scales. I work on a preview at 1:1 or higher zoom to check the effect and always err on the side of caution. It's really just a small scale smoothing of the background areas rather than full-on NR.
The thing I really can't decide is whether it is better to do this NR before or after deconvolution. I haven't been able to detect much difference so maybe it doesn't matter?
Cheers,
Rick.
