As a matter of fact, our eyes (mind) works differently from photos or computers. i.e light attenuation is based on inverse square ratio, but when one adjusts them in this way will find it more like what a camera captures and not what our eyes captures. So I've experienced that it will give a better result if adjust the attenuation as "inverse". the result will be more smooth and less contrast ,a better solution for interiors. and do not neglect some fake lighting using rectangular lights, here and there ... 😉.
