I've been experimenting with Noise Ninja a bit, but am still not up to speed on the best settings / workflow with this plug-in. As others have noted, the default settings are rather strong and often do result in considerable smearing of detail. There are three sliders under "filter", and I've turned these down to about half their default strength as a good starting point. Then I try playing around with Edit > Fade Noise Ninja and try to find the best tradeoff between sharpness and noise reduction. I need to start trying the spot noise reduction tool, but haven't gotten around to it yet. What is your workflow with NN? Any other suggestions?
Thanks,
Kevin
