This tutorial dives into the nuances of using diverging light sources, like projectors, to enhance your sketches.

We saw previously at the How to Draw Cast Shadow using PARALLEL source light (such as the sun).
Today let’s see more about DIVERGING source light (such as 1 or multiple projectors).

The “Diverging source light” would fit better for objects you could hold in your hand for example.
