This is interesting...where an object has light shining on it, there is no shadow. It is on the side that is turned away from the light source (the back side) that the shadow appears. The shadow appears because it is the spot where there is less light.
Artists do not draw or paint objects. I know it looks like they do. But what they draw or paint is just the effects of light and shadow. You cannot portray an orange without light and shadow. It would just appear as an orange circle and would not look like an orange.
Even someone who is not an artist can try this experiment to know that it is so. From memory, without looking at a nose, try to draw the shape of it. You will only end up having drawn a symbol of what you imagine a nose to look like. But then, look at an actual nose and try to draw it and you will be doing nothing more than drawing spots of shadow to portray it. It is the effect of light on an object that gives it its' turning or three dimentionalness.
