Rawpedia – Local Adjustments - has been updated to « Differences between Lab* in Local Adjustments and RawTherapee in general ».
Thanks to Wayne @Wayne_Sutton for his help and translation.
It concerns the modules:
- Sharpening,
- Contrast by details levels,
- Blur/Grain & denoise,
- Denoise,
- Log Encoding,
- Color Appearance (Cam 16 & JzCzHz)
I put as an example in front of the introduction concerning “Denoise”.
This module is quite different from the main-menu noise reduction module for several reasons:
- It is equipped with a non-local means or piecewise denoising module that only deals with luminance noise.
- It uses the same basic wavelets functions as in the main menu Advanced tab, modified to increase the number of decomposition levels:
- The number of luminance levels has been changed from 5 (0 to 4) to 7 (0 to 6) to better differentiate the noise reduction especially in uniform areas (requires more resources).
- The number of chrominance levels has been changed from 6 (0 to 5) to 7 (0 to 6).
- The following additional functions have been added:
◦ The DCT (Discrete Cosine Transform) algorithm has been extended to the chrominance component.
◦ The ability to combine the wavelet actions with other tools for difficult images. For example, the Guided Filter, which will act a bit like a bilateral filter, especially for the chrominance part.
