noise preference

I am currently studying noise reduction using Rawtherapee 5.0.
Can anyone explain the meaning of the following preference settings under the performance & quality tab:
Cell size, denoising level, tool mode, auto multi-zone smoothing, number of tiles, increase wavelet level in quality “high” or refer me to documentation that explains it.

Morrn, da!

Most probably @Morgan_Hardwood :slight_smile:

My personal favourite is Denoise (profiled) in
Darktable, though.

Have fun!

The Noise Reduction and Preferences pages in RawPedia need an update, but there is some info there:

Hi’ Morgan
Thank you for your answer. I was studying the documentation on noise reduction (same as in your link), but there is no explanation to the different settings when you read the preference tab documentation. Maybe I can deduct this from a detailed study of the general noise reduction description?
