How to draw Cast Shadow with Diverging source light easily!
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).
To illustrate both techniques, let’s consider the volumes in the videos to be something you could hold in your hand. Basically, I consider that the “Parallel source light” would come from a (huge) wide source of light such as the sun.
The “Diverging source light” would fit better for small lights such as projectors.
Note: It’s all about scale.
If you draw an entire city with high buildings, from an eagle viewpoint, you could use the Diverging source light. It may give a more “dramatic” result.
Choose the graphic impact you want to give to your sketch.

Cast shadow with 2 projectors
Cast shadow with a closer projector to the volume.
Try to draw a few and test a minimum of 5 different source of lights.
Take a pen and let me know how it goes in the comments below !
Note: Do not train using any ruler to trace the straight lines.
It’s a good habit to take from the start.

“Hi, my name is Di from Jakarta.
Thanks for sharing your experience.
I’ve been searching for good resources to train my sketching skills, especially a product design sketching style.”
