Sharpening with Blur

[Italian74]

In Photoshop images are often sharpened using an iverted layer with blur. This gives much better results than unsharp Mask. Has anyone tried this method in Gimp?

As far as I know it is as https://www.gimp-forum.net/Thread-Look-m...-Gimp-2-10

Should be the same with Gimp 3

All these methods (including the official sharpening tool) work by subtracting a blurry version).

In Gimp3 you can do even better because you can set the blur as a NDE effect and tweak it later.

Google AI : an NDE effect refers to the profound after-effects experienced by individuals who have had a near-death experience (NDE), including increased spirituality, a reduced fear of death, and a deeper appreciation for life. Blur ?

"NDE" in this context is "Non-destructive Editing", not "Near Death Experience".

It means that when you apply a filter, it's not immediately merged into the pixels (like in 2.10), but floats above it. You can merge it later, or go back and adjust the settings to changes the effect - without undoing your prior work.
