You can't. When light is low or poor quality, you get noise. You can try to hide it by using NR, increasing contrast (clip blacks), reducing saturation, etc., but personally I would not change my desired rendering just to reduce noise.

You can use various types of noise reduction in post, but they all have negative drawbacks (such as loss of resolution for noise reduction).

That is not going to reduce noise. At best it will reduce clipping.

None of those are any use for reducing noise in low light.


Good luck.
