Noise Reduction has been improved greatly in recent years. Now that AI has been more common in image editing software the noise reduction has become even better.
DxO PhotoLab 4 is the best one on this right now. Its DeepPRIME algorithm does astonishing work reducing noise.
DxO PhotoLab 4 is part of my workflow.
I use now DxO PhotoLab 4 for my noise reduction. It also has the tools to correct distortion, vignetting, CA, etc. on images. It has tons of modules for different camera-lens combinations. Images look so much better after going through DxO PhotoLab 4.
What is great about DxO mark is that it works with older cameras too. Here is an image from 2015 photographed with E-M5 MKII and M.Zuiko 25mm f1.8 lens. The ISO was ISO3200.
As you can clearly see how much better and cleaner the lower part of the image looks. You probably guessed that the lower part is from the image that was edited with DxO PhotoLab 4. I only used DeepPRIME and lens corrections. That way there is slightly different cropping. DxO PhotoLab 4 has made a lot better job fixing distortion etc.
Correction Modules for camera-lens combinations
I did not have the module and DxO PhotoLab 4 automatically suggested to download the module for this combination.
DeepPRIME does not ruins the details in your image.
Below is an image from November 2014. It was photographed with E-M1 and M.Zuiko 12-40mm f2.8 Pro. I used ISO3200. This image has a lot more details and DxO Photolab 4 made an excellent job getting rid of the noise and still it was able to keep the details in the image.
