P: Noise Reduction not available for S21

Thanks 

It worked fine for samsung s10+ DNG files

This issue first appeared with camera raw 12.4 and now 13

It's gone unnoticed 

Same for the S21 Ultra on Windows 10 with Lightroom Classic V10.1.1.

Go-around while waiting for a fix (has this been reported to Adobe yet?), go negative with the texture slider. At least for the S21 Ultra raw images, going negative reduces noise (as expected) but also increases sharpness. Not sure if this is a bug with the texture slider as reducing noise is a little known trick that occasionally increases (apparent?) sharpness.

Thanks Bill.  It's just frustrating as I "upgraded" from the S20 to the S21 to get the "better" camera and now I'm in far worse shape than if I had just stayed with the S20.

What's the saying?  If it ain't broke don't fix it?

Confirmed your observations with the 23MB image. None of the sliders in the Noise Reduction panel have any effect. All the sliders in the Basic, Sharpening and Transform panels work. 

I did find that reducing the Texture slider cleaned up the image but also increased detail so I'm suspicious that this slider is not working correctly. My experience with other images is that taking this slider negative reduces sharpness. So I guess that temporarily, this could be used for noise reduction. As this slider is just a smart combo of Luminance Noise Reduction and Sharpening, the same result can be accomplished by using these 2 sliders independently. 

I redownloaded it and this time it is 23MB with the exif data. As the prior image wasn't overlaid (changed the name first), I can compare and see that the first one was only 1/2MB. Tomorrow I'll load the full size image into Lightroom to see how they compare. 

Strange. When I extracted it to my hard drive, it was only 1/2 MB. I gave up on One Drive a couple of years ago due to all the bugs which never seemed to get fixed and switched to Google Drive. Is it possible that your upload compressed it in some way or perhaps the extract to my drive? Google Drive has 2 modes: free and fee with free compressing. Is it possible that One Drive does something similar? 

Agreed, but the luminance noise reduction is typically much more aggressive.  There is no doubt it isn't responding to commands.  My other DNG files from my S20 are very responsive to the noise sliders, so much so, I typically just bump it one direction or the other to not overdo it.

I'm not sure why you're not seeing the EXIF data.  When I open it in FastStone, here's what it shows, attached.

Thanks for asking, they do not work at all, none of them in that section.
