Plotting Cast Shadows in Your Drawing Successfully
Plotting cast shadows can make or break your drawing. It might not jump right out at you but your brain realizes that something is off. It’s very much like if your perspective is off in your drawing.
Why? Because plotting cast shadows IS perspective. That’s how it works.
The reason why you can’t just slap a shadow down behind an object and have it look right is because shadows don’t just fall at random locations. Shadows are not haphazard. They have to follow the same rules of perspective just like the rest of the objects in your drawing. That means they are very predictable and very plottable. If you have one light source, all shadows from all objects must follow the light source correctly in order to understand the light and where the source is in your drawing.
In a previous post, I gave several examples of plotting cast shadows with a light source coming in from an angle. I did not illustrate in detail how to plot shadows with a single light source directly overhead. The example I’ll show you now is a single light source directly overhead and between three objects.
