Noise reduction settings mixed up

It seems that the extreme noise reduction gives the smallest amount of noise reduction and also maintains the finest details, at least using it on jpg.

Extreme < Normal < Strong, so it seems that Extreme should be Normal, Normal should be Strong and Strong should be Extreme.

This has been the case for a while (I noticed it the first the for a month ago, but it is possible that it has been so for a longer time) and I see this on different computers also

From my tests this was not the case so I’d like to see what the situation is with your images.

The first file is from 2005 and taken with a Canon 20D and I added screenshots of the three different modes. There is also some strange ghosting effect from the wires connecting to the bridge, which you can see on the full image.
The next example is from 2018 and taken with Samsung Note 8 and it is not as evident as with the first photo, if you look at top of “Stadshuset” in green, it is more deformed with normal than with extreme

Thanks for sending the files. I was able to review and see what you are talking about. Do you mind if I share this with my team so we can have a discussion about it?

The models work differently so some variation in results is expected. In general, we found that the Normal and Strong model produce better results.

If you prefer the Extreme model, there is an option to use it by default in the Preferences > Autopilot menu here:

No problem, please use it anyway you would like.
