Excuse my bad English, I’m a grumpy old French.
I like to develop algorithms, some are simple, like Lab, others more complex like Retinex, others even more like Wavelet, or Locallab.
But actually, there is a lack of tutorials (and translation from french in some cases) for Rawtherapee, especially for algoritms that come out of “common sense”, such as Retinex, Tone-mapping or Wavelet.
Wavelet does not limit itself to a restricted view which consists of using only the contrast sliders.
Many innovations “wavelet” , especially for this image, can be used to reinforce the effects of contrast and perspective,
for example “Residual image” and “Final touchup” (compression, contrast balance, etc.)
Paradoxically I am not a treatment specialist: what treatment for such an image? So it’s not me who will develop the tutorials
But the result is above all a matter of taste
