Denoise AI is a superb tool to remove noise without losing details, and it works well in many cases (planets, nebulas, clusters...). It gives a nice final polish, and could even bring back to life some old pictures I considered lost. I use it as a standalone application, not in PS.

​

Some caveats:

 

• It may induce some artificial patterns (oriented grains, small tiles, or "crocodile skin effect), or small unnatural artifacts so one must be cautious.

• It seems that the intensity or location (to a lesser extent) of these patterns depends on the region of interest selection, so checking the tweak in different regions of the picture is a must.

• Always save pictures versions with various denoising intensity as in the heat of refining settings, it is very easy to end up with over-processed images.

​

Some features that could be implemented to improve user experience:

 

• Having the left comparison window offering the last tweak beside the initial image, to better refine settings

• Processing time may be a bit long (10-30s) especially when experimenting with several settings combinations.

​

Example of use can be found here. Overall a great addition to my range of processing software. Topaz Labs also offers such as Sharpen AI and Gigapixel AI (picture size enhancement) that may worth to test.
