Denoising with Topaz Sharpen AI

Topaz Sharpen AI's sharpening wizardry is amazing.

But the app can also do excellent denoising if the image has been pre-sharpened to the exact degree that suits TSAI.

Below is an ISO 12800 image processed in DPP and therein sharpened to level 0, 3 and 6 resp., before being converted and saved to 8-bit TIFF.
Bottom row are the corresponding images after being further processed in TSAI (mode Out of Focus - Very Noisy) with Suppress Noise set to 100.

All pictures are screen shots of 200% views of final JPG files.
