@garagecoder, thank you. Please also keep the current “Tone enhance” filter, because of the big change.

After refresh, your new filter isn’t there yet. Although I am very curious, I will wait patiently for an G’MIC server update.

edit: It is updated, so now I can test.

Description under filter "proposed update to Tone Enhance"

Again, please keep also original filter, because that is already useful. Maybe other people want also keep the functionality of original filter, so please make this filter after testing available as a new filter. Or make original functionality available within the new filter. Thank you very much.

edit2: I am very happy with this filter. Because of available color spaces, you can now see the different effects (saturation, contrast, lightness etcetera) these color spaces have, with using this filter.

edit3: These filters are also very good dehaze filters. (play with cut and normalize)

edit4:

After some testing I can say, I realy like this filter, It is nice to be able to change the gamma. I have the feeling that there are less “gradation artefacts” now you can change the gamma instead of brightness. But I miss the opportunity to set the overall brightness, so I have few wishes : Please add sliders for contrast and brightness for final editing. If it is possible (and takes not to much time, it’s no big wish) also (a) slider(s) for saturation.
