Cast Shadow | Parallel source of light from the Sun |TIP109

To make your sketch pop out from the background, it’s essential to add a Cast shadow. The “cast shadow” projects the shadow of an object on a surface (basically the ground surface).

I basically use 2 methods at drawing the cast shadow:

  • the Parallel source of light
  • the Diverging source of light

Let’s see today the most simple one, the cast shadow with the Parallel source light.

If the sketching methods I’ve acquired aid me in my life and in my career, I believe that they can also help you to learn, and help you with your projects. Whether Design is a job or a hobby it doesn’t matter, so long as you do what is important to you.

      Hello Irene, at start you can help visualize the ground plane by tracing a quick grid like I did at the beginning of the video. Remember to trace it with a light pen pressure – or your drawing will be over crowded of lines.
