Manual Noise Reduction isn't show up in Library module and won't be exported

[Lennart311862854746]

Hi!  I need help!  I use LrC's Manaul Noise Reduction to clean up the noise of a jpg file.  I was happy with the result.  However, when I go to the Library module, the NR effect is not showing there.  The original noise is back.  When I export the file, the same thing.  The Manual NR effect isn't applied.  I am using LrC v. 13.2.  Any idea why the manual NR isn't applied beyond the Develop module?  Thank you very much!

I probably should have mentioned two things:

- I am using macOS Sonama 14.2.1.

- This is the first time I have used Manual NR.  So, I might have missed some steps to apply the effect but I couldn't find anything on it.

When working with noise, sharpening and other image detail, you must view the image at 100%. (if you have a 4k or higher resolution monitor, you may need to use 200% because the pixels are so small)

This this the only view that presents you with a true representation of the image – one image pixel is displayed using one screen pixel.

Any other view will be inaccurate and misleading because the image has been scaled.

You also have to view the exported image at 100%.

Also remember that you have to export a new jpeg in order to apply edits. So do not export 'as original', thinking that this will work because the original is already a jpeg.

Correction, the original file is a PNG file.  I am exporting a new jpg file.  Does that make a difference?

Thank you for the tips!  To be honest, I am not sure if viewing 200% helps me at all.  Not because the tip wasn't helpful, it was more about the fact that the photo was way too noisy.  I take a photo of my father's passport-size photo using my Fujifilm X-S10.  I am doing that because I need to blow up that particular photo for a print.  The RAF file was blurry and already noisy.  After I used Photoshop to sharpen the photo, the noise level is just incredible.  That's why I want to clear out the noise but I am not sure if I was very successful.

Sharpening can easily exacerbate image noise. There are strategies for reducing that and also one can apply noise reduction. One thing you can try is leaving sharpening low, and experimenting with the Texture slider which addresses larger-scale detail within the image. Assessing a mixture of useful image detail vs problematic image noise can be really difficult, since it's very sensitive to expectations. Different zoom factors further complicate this assessment.

Often even a well taken and processed image may have a somewhat grainy look as judged at high zoom on screen, yet still in practice be very suitable for printing. But blurry and noisy is more problematic - that sounds more like a misfocus or camera shake matter  to me, which may be worth a re-shoot if possible.

So far as making the best from what you can capture, I would recommend trying the recently introduced AI Denoise on the RAF image and then comparing how well that processes out. This creates, and imports, a separate cleaned-up DNG file alongside the starting out-of-camera file.

I agree with @richardplondon that working with the RAF file should give you the best result.

Turn sharpening off completely, then run DeNoise. You can then try to sharpen the new denoised DNG.

To prevent the sharpening of any remaining noise, use a high Masking value. This prevents flat areas (where noise is most visible) from sharpening.

You can preview the effect by pressing the Option key while dragging the slider. White areas will be sharpened, black areas will be protected. Make sure to also view the image at 100% while previewing, and after letting go of the Option key.
