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.

  • your cylinder does my head in,I thought the light source had to be shown at a right angle to the floor but that just looks like you have drawn the light on the rail at the top, but at the front of the cylinder and then connected it to the floor at the back. 🙂

  • i’ve never seen someone teach shadows easier than this 😀 … thanks alot for sharing this with us ^_^
