Alfonso, sorry to do this, but i think your answer is just a distraction from the information YangDaniel needs.
We are talking specifically about turning form with light, which is something you can only answer by focusing specifically on that issue. My problem with things like the link you provided, is they don't go into the form value relationship at all, and instead it just becomes a laundry list of observations about the world, not explanations. Hell that first ball illustration is inaccurate to the point of it being useless.
Almost 100% of the time peoples issues with describing form with light isn't if they are considering ambient light and ambient or not, it comes from simple light plane form turning.
I think you should go back and read my post talking about Lamberts Cosine Law (which was a link btw).

Drawing out of perspective is like singing out of tune. I'll throw a shoe at you if you do it.
