Photoflow: luminosity masks issues

Sure,

@RawConvert Could you please repeat this question in that thread? I think it belongs there.

@RawConvert Anyway, I don’t know the answer, but I suspect that the blur layer above the curves is to address the issue. From my experience on this exercise, I realized that tweaking the blur radius, as well as the mask slider, you can’t get rid off the artefacts.
