I love it! There is a light technique associated with Caravaggio called ciricocho (?) or some such thing that was used in the movie Blade Runner according to a postmodern prof I had in comparative literature that would make us read Stephen King novels as literature and host of other trashy books that I can't remember to save my life. But I do remember the reference to the light technique which I thought Caravaggio would never have dreamed that art students would be talking about 100s of years later unless he was in a bar and lucidly prophetic to the temptations of sin and seeing Gods plan for all sinners unfold into the future to the point where postmodern sinners could talk without any reservation about God grand mastery of light that reveals humans, as not politically correct, but as obscured as their words and deeds... no light there on the surface.

Are you thinking of chiaroscuro? Light/Dark? Leonardo was the first to use such dramatic contrasts, but Caravaggio took it to a new, dramatically lit height.
