I am using the stable 5.8 version of RawTherapee. While editing files from my Panasonic FZ330 camera I have noticed a loss of saturation when I enable the default noise reduction, especially in areas where colourful details are small.
Here is an example. Please look at the leaves and the moss covered branches and rocks. Left is the camera jpeg, middle is RT5.8 with noise reduction enabled and on the right is RT5.8 with noise reduction off. Is RT mistaking small areas of colour as chrominance noise? Is there anything I can do about this without having to manually adjust the chrominance noise settings for each image I process?
Here is the raw and camera jpg.
