I’m really liking the effects Raw Therapee is giving me, but I’m wondering… is there a blending tool that can help fill in this kind of post-noise-removal dot effect? I feel like there should be, and that it’s possible. I could do it with blur/healing and a lot of time and effort in Photoshop. But is there a filter I can use?
The example is showing that the “dots” are actually image pixels and the teeth are only about 8px wide.
What noise-removal did you use? Doesn’t look right to me.
Can you post the raw original?
Ah. It’s just a screenshot as an example, the actual dots are wider spaced. I also upped the noise removal to make it more obvious. But you can see it here:

In the Preprocessing panel of the Raw tab is a tool called “Line noise filter”. You might experiment with that to see if you can get a satisfactory result; but, an ISO of 20000 added to significant underexposure really stacks the deck against you.

Thanks for the raw. I cropped it and scaled 2X with no interpolation so as to see the actual pixel (not screen) noise. Also applied brightness and contrast to bring out the noise. See right side of the pane. There, the Signal to Noise ratio is 2 (6 dB).
Doesn’t look recoverable to me but I applied 6.18 px Gaussian at left, just to see:
Thank you, what program is that?
Yeah, I pretty much had to to get the shot I wanted in that environment tbh. It was that or drop the shutter to a blurry degree.
