Just to throw in my 2 cents, can I ask where this image is going to be used? I ask, because I would consider the amount of noise in the image to be below the level you would get from a real world photograph.

If this is a frame from an animation, then this grain level is far below the level that ...

I recommend that you blur the HDRI, especially given how you are choosing to use it. High frequency details in the image can contribute to noise. Blurring the image can reduce those artifacts, yet still give you the illumination you prefer. Affinity Photo is a good (and free) option here...
Thank ...

Can we see the HDRI you are using?
I'm using this one from polyhaven in 4k resolution https://polyhaven.com/a/studio_small_09
As a side note, it could easily be all done without an HDRI.
Studio lighting is actually best without it. Much more lighting and sampling control. It is night and day ...

It looks "clean enough". It's either a matter of subtle tweaking or gentle denoising.
I set adaptive sampling according to noise map, so I think this parameter is right.

I'm sorry if I bored you, I just have this problem often and I would ...

Changing the amount of samples is not doing much difference. Also, I set adaptive sampling according to noise map, so I think this parameter is right.

That’s looking pretty clean but yes DoF can be quite expensive. Your settings look good I would suggest using the denoiser as well and you could blend between the denoised image and the raw beauty so you can recover fine details. Otherwise I sometimes need 8-10k+ samples in extreme conditions ...

Hi,

Usually, it's often the following:
• Plausible shading (especially specular reflection always requiring a minimum amount of roughness, and refraction)
• Appropriate lighting (avoiding extreme "intensity values")
• Tweaking Adaptive Sampling (requires the "Noise" AOV, otherwise it's hit or miss ...

Hi, all!
I have an issue that is coming with me from project to project and I don’t know how to solve it. The issue is a noisy blur when you have camera depth of field (see attached, denoiser is turned on). The more depth of field I have, the more noise it has, without the depth of field image is ...
