Lightroom Classic CC Noise Reduction was not implemented on Picture

[danjelr53547816]

Hello Adobe Support,

with the new Version of Lightroom Classic CC i have a Issue. I have Pictures imported in the old Lightroom CC 2015 Version and be converted in new Lightroom Version. When i go in the Develop Module and begin set Noise Reduction. I can not see any changes in the Picture. But when i switch in the Library Module i can see the Noise Reduction on the Screen. It was very difficult edit my pictures with this Issue.

The Picture was imported as RAW File and converted to DNG. The Preview Rendering was made on 1:1.

I have Windows 10 with newest Updates.
Intel I7 Hexacore CPU und 16gb RAM
The HDD is a Flash Drive.
I have a 4k Monitor from Samsung

I have made change settings: I have activate the GPU Rendering. But the Issue i can see befpore the changes.

I attached a picture then you can compare the Library to Develop Module

Are you judging the noise reduction while zoomed in 1:1 in Develop and comparing to 1:1 in Library? It wasn't clear from your writeup. The noise reduction preview in Develop is only accurate at 1:1 zoom levels for speed reasons so you really should only e touching the sharpening and noise reduction controls when zoomed in at 1:1 or greater zoom levels. If you are judging at 1:1 it is possible that the updates in Develop are sluggish as you are using a 4k screen although this computer is quite the powerhouse so that's probably not it.

[danjelr53547816]

The Picture was not compared on 1:1 Zoom. It was in the fitted mode. But the Workflow of the Picture is not always set to 1:1 Zoom. That was not practicable and confuse me. In Lightroom CC 2015 was the fitted view correct and i can see the correct development. This behavior was in the Past on Lightroom 5.3 similar.

I have delete the caches and the Issue was always persistent.

Any view other than 1:1 or higher zoom has never been correct in Develop with regards to noise reduction and sharpening. This is a long standing issue that many people have ran into. You only see this if there is significant noise in the original so most of the time you would not have noticed. There are probably hundreds of threads on this on this forum. So you really should ONLY touch the noise reduction and sharpening at 1:1 or higher zoom.

[danjelr53547816]

Sorry but thats not correct. The Issue was not present on LR CC 2015? After the Update the Issue was come out?

That can not be the explanation.

hardliner

[Jao vdL]

Yeah it has always been there. It’s why the panel shows a little warning sign if you’re not at 1:1

[Per Berntsen]

My copy of LR Classic displays noise reduction in Fit view exactly the same way as CC 2015 - i.e. you can see that noise reduction has been applied, but it's not accurate.

As pointed out by https://forums.adobe.com/people/Jao%20vdL, noise reduction and sharpening can only be evaluated accurately at 1:1 view, where one image pixel is represented by one screen pixel.

This is not really an issue with Lightroom, but will happen in any application when the image is scaled to any other magnification than 1:1 (100%).

[gvir]

I have the same issue, and i am sure it is not a problem with the Screen Pixels. I also did not have the Problem in the previous Version. Fact is, that the Picture is showing correctly in the libary modul, and for a second also in the develop modul. but after a second it seems, that LR disabels the noise reduction.

[danjelr53547816]

Hi all,

i know that the best adjustment for noise reduction sharpening make on 1:1. But you can not always be on the 1:1 View. You go back to fitted view. And here ist the normal workflow. the deactivated noise reduction and sharpening confuse me in the workflow. Always i mean the picture is not correct and make wrong adjustments.

And really the behavior was not in LR CC 2015. In the Library Module was the noise und Sharpening in the fitted view correct.

I hope the Support can here fix the Issue.

Danjel Rojka

[Jao vdL · Accepted solution]

danjel in another thread it turned out that the issues somebody was seeing was due to a problem with the GPU acceleration for certain graphics cards and operating systems which is why only some people might see this. Try seeing if turning off GPU acceleration in Graphics->Performance changes this.

[danjelr53547816]

That's it. I change the GPU Acceleration  and in the Development Module i see the correct view.

Its important to update the Grafic Card?

But the question is. is the GPU acceleration needed to boost LR Classic CC?

Or the Performance boost is minimal?

Best Regards

Danjel Rojka

[Jao vdL]

You should keep the GPU drivers updated indeed and I also think that Adobe will probably fix these bugs soon. The GPU is quite essential for the speed improvements that were made in Classic so yeah it would be better to have but if you get display artifacts that negates any speed improvement!
