Hm, I get the feeling that this decorator gets too complex and "magic"… Is this really a standard use case? If someone really wants to apply a filter to the luminance channel of an image, why not let them use ***2lab function?

I agree that documenting the extra filter parameter could be problematic. I guess that the decorator could inject that into the filter's docstring, but that's probably too magical. We could make it a hidden parameter and provide utility functions that just change the default behavior.
I'd prefer for the parameter to be visible and documented for each function that chooses to use it. I think we should just make application to each individual layer the default, since that's the most obvious generalization to RGB.
