My 12 year old granddaughter didn't love it. Too, too noisy. So fix it. grandpa. (Got her RT trained since she was three and I gave her a big girl camera that took pictures of her feet and her cat and herself in a mirror)
Grandpa's two minute fix. Far less noise coupled with slightly more sharpening. The S/N was measured using ImageJ
****
The idea is to remove as much noise as possible and not worry about the sharpness. So there is nothing magic about the 91.59 luminescence. Could have been 100% if this wasn't a two minute fix and I had been paying more attention to the GUI fit on the screen.
****
Increasing the edge sharpness strength to 34 restored the original sharpness. Some small artifacts showed up as bright spots at 300% magnification. Using the denoise section of the tool removed most of them. I should note that the tool is still being debugged and improved so these minor artifacts may not be a problem in the next build.
Final note. The denoise slider numbers in the history panel are the correct numbers. The slider settings on the right are the defaults when I set the sharpening strength.
