I have to give some credit to the new AI RAW Denoise
I had wanted to be hyper-critical of the AI RAW denoise in the new 5.6 release but then started using it and I'm pretty impressed. Took some night safari shots at Singapore Zoo at ISO 32,000 on my Sony A7RV, so not the best performing low-light body but no slouch with a full frame BSI sensor. Using profile denoise produced acceptable but still noisy results with a fair amount of detail loss. The RAW de-noise however was very good, retained detail like fur and whiskers well. For comparison I have the civet but using profiled denoise, which is still doing a pretty respectable job, but in my opinion the AI RAW denoise is better.
Apologies about the images, I have a bit to learn about low-light photography, but was fun to play around with the new denoise function and see that it is quite usable.
