RAW files grainy

[Cinzia3604582858vf]

Hi everybody! 

I updated my old lightroom some days ago but now whien I import my RAW files in lightroom 2024 (Mac OS version) they are VERY grainy. If I apply "AI delay noise" the pictures turns normal but my question is: is that normal? How can I fix the problem? I do not want to apply the "delay noise" everytime and to all pictures as it is really a waste of time! 

Can someone help me?

Thank you!

Lightroom (Lr icon) or Lightroom Classic (LrC icon)? What version NUMBER?

Please show us a screen capture of one of these grainy photos as it appears in the Develop Module. We need to see the entire develop module screen. Please use the "Insert Photos" icon to include your screen capture in your reply.

Hi!

thank you for trying to help me! 

here you find 2 screenshoots: the first i hope you can see the grain, the second one is after the application of AI noise reduction (or DENOISE AI, my LrC is only in Italian, sorry). 

I'm sure that the image produced from my camera has not that grain as I already imported it in my MAC before the updating of Lightroom. 

Shoot with Nikon Z6ii, ISO 800 (I also shot at ISO 1250 with NO grain/noise)

Lightroom Classic last release 13.2

The picture has been imported with NO presets or develepment settings, as far as I know. 

Thank you!

Thanks for posting the pictures. Like someone else mentioned, I can't see the noise issue.  May be you have a better monitor than I do.

In trying to help, I found a post where it was stated "So, for the Z6II the best ISO is base 100. But its dual gain crossover is 800. In theory, whilst ISO 100 will always perform the best, the charts will says that when you need to up the ISO you should jump to 800 as it will perform better than the in between ISO values such as 200, 400 etc." 

You may want to ask your question on the one of the Nikon forums like Nikonians.

This is generally referring to the Dynamic Range of the sensor/camera combination, not noise.

This is completely normal noise for the conditions and what you need to realize is that Lightroom shows you the actual noise in the image. The jpeg preview image that is embedded in every raw file and which is what many programs show you is heavily processed by the camera. You don't need to run this through AI denoise. Just optimize the detail and noise reduction sliders and you'll be fine. Nothing wrong with running it through AI denoise but it is not necessarey for very light noise like you see here. Also you can try just applying the camera settings preset to this image. It will apply more aggressive noise reduction based on the settings the camera applied. This can also be achieved by using the preferences to apply camera settings by default. This works really well for the Z6II and will make your images very close to the jpeg preview out of the box. https://helpx.adobe.com/lightroom-classic/help/raw-defaults.html That will apply to new imports. For already imported images simply apply the camera settings preset.

• Which version of Lightroom Classic are you using? The current Lightoom Classic versio is 13.2. 
• When you say "AI delay noise" are you referring to Lightroom Classic  "Enhance ->Denoise"?
• Are you applying any presets or development settings when you Import your RAW files?
• Which camera produced the RAW files?

[Jao vdL]

With most images, you should be able to just optimize the settings in the detail panel Noise reduction section. Only do that when zoomed to 1:1. Denoise AI is only really needed for images shot in very low light conditions and even there you can usually do just fine with the standard noise reduction. Do know that Lightroom by default applies very moderate noise reduction and many cameras apply extremely aggresive noise reduction to the point of pasting over actual details in your images. Lightroom shows you the actual raw data and you often have to do a bit of optimization of the sharpening and noise reduction settings. Luckily with a small amount of practice this is extremely quick and you can develop some sharpening and noise reduction presets.

Camera type? ISO?

Have you tried using the LrC "Camera Standard Profile"?

Hi! Nikon Z6ii ISO 800

I will try your suggestion, thank you!

You are viewing the image at 173%, which will make the noise more prominent, but I cannot see any noise in the image, and it certainly does not need noise reduction.

When working with noise, sharpening, and other image detail, always view the image at 100%.

This is the only magnification that gives you a true representation of the image, because one screen pixel is used to display one image pixel. Any other magnification will be inaccurate and misleading because the image has been scaled.

In the future, please do not attach screenshots, use the Insert Photos button in the toolbar to insert them directly into your post.
