Here was a fun experiment. Here are the original, a copy processed with minimal noise removal (-10 on the default sliders), a copy processed with the default noise removal plus 50% sharpening, and a copy with enough gaussian blur to approximate the amount of noise removal in the 'minimal' copy. I used the profile for Panasonic LX3 ISO 400 provided by the software.
I'm liking what I get somewhere between the Ninja_Less and Ninja_More copies.
NN seems to work well on this type of image, but not so well on trees and foliage, which appear to blur too much no matter what I try.
These crops are 100% - no size reduction.
