Luminosity selection with Select Sampled Colour

Recommended Posts

I did a Select/Select Sampled Colour. Then selected Model: Intensity. Then clicked in image. It looks like I'm doing a luminosity selection. I can even adjust the width with Tolerance.

 

Underlying question I'm not sure about: Is Intensity the same as Luminosity? If it is different, then this would still seem to be a way of doing a luminosity selection if a b/w conversion was temporarily inserted beforehand.
