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

      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.
