Why would you want to use the equalizer? I mean, if you have a type of noise that the dedicated de-noising modules are suitable for and more effective for than the (more general purpose) equalizer, why not use them?

Hi. I'm trying to understand the equalizer better. I have an image shot at very high ISO: https://www.dropbox.com/s/gkrcxshydk0slfc/DSC04403.ARW?dl=0 I want to denoise it using the equalizer. But no matter how high I drag the denoising curve, there is still high frequency noise in the image: https://www.dropbox.com/s/r7rxhgkzapdz72e/chroma_noise.png?dl=0 Is that expected? I would have thought that I can completely remove this noise. Using the profiled denoising with wavelets, I can easily smooth over it. I thought the equalizer could do the same. I'm using 2.2.4 Thanks!
