Hi MxHeppa,

Using R, G and B (they need to be in caps) you can target the channels of the original image and then use various common math functions to manipulate the channel information.    For an example of this, see this tutorial which covers creating a tone mapping effect BUT it's a good example of how this filter works

i bet same way LAB and CMYK?

Hi MxHeppa,

If you have an image the LAB Colour Space when you use Filter>Colours>Procedural Texture this dialog will then reflect the LAB channels   You can't use the Live Filter version of this filter as that only applied to RGB at this stage.

imean if i want process CMYK data i have CMYK parameters similar way and in LAB same. but in these modes i cannot access RGB chanels of course but only LAB Or CMYK or RGB.
