I have questions for those who are very familiar with this topic. Is the reflected light always present? Are there circumstances in real life where this reflected light is not visible like the 3D examples in the original post?
I'm no science expert, but light does tend to bounce on surfaces in real life all the time. One assumption that can be made is that the stronger the light source, then the more evident the light's reflection on surfaces is going to be which will consequently effect how strong shadows appear.
Though that may also depend on how many light sources (diffused lights especially) there are since chiaroscuro style painting and lighting tend to use very strong light and very deep blacks with little reflections and rebounds evident (just look at Caravaggio’s paintings and Clint Eastwood’s films such as Letters From Iwo Jima). Colour may also be a factor on how much light is reflected since dark surfaces tend to absorb light and heat while brighter ones do the opposite.
I guess the short version to my answer would be; it depends on how many surfaces the light is going to bounce off of. Then again, it could be a lot more complicated then I made it sound.

This thread is awesome!Thank you so much for starting it - I am just copying on color paper with black and white grey scale images of the simple shapes before I start into color - and there are few questions I wonder if somebody could answer to - it would be very helpful!
So...when we have a sphere everything is fine,but then - when we go to the pill shape ( I have no idea what would be the real name of this shape) or the doughnut I have troubles with the top light - it looks to me like there is a lighter border just next to the background - is this an illusion?Also I just want to confirm - is the occlusion shadow just a hint?If we have to gradually distinguish the values - the terminator would be darkest,then the occlusion,then the halftone?Would the halftone spread in same value on both sides of the terminator?
Yes mate the torus is a pig to do sometimes but just observe it and carefully put down on paper what you see, that's one of my problems i tend to put down what I want to see or what I think I see and that's when it goes wrong...................
i am glad you like the thread and are getting something good from it, that's why I started it and also why they stickied it, which I still get a warm rosey glow from ...LOL.
all the best and keep posting your questions, there is always someone around who will take a stab at answering them.
Not sure how active this thread is, but I've been hitting these fundamentals hard so it'd be nice to have a place to show some work off/get some pointers from people on how to get more realistic results.
In answer to your question MrFrenik its a very active post/ sticky and those are pretty good.
I do have a minor point about the cube though the angle of the shadow seems to be wrong, I say seems to be wrong as I cant quite decide if it is or isnt due to the strength of the light source! HELP ME SOMEONE!!
