Clarification on the use of the terms 'Brightness' and 'Luminosity'

[Boudewijn Rempt]

Technically, luminosity refers to how much light a given body emits, while brightness refers to how much light a body reflects. In practice, which term is used in which context in English depends on custom, in particular on where Photoshop uses the terms. I don't know whether it's possible in Italian (especially since I don't have access to an Italian copy of Photoshop...) but it would be good to keep a consistent and distinct translation for both terms.
