Mini-Tutorial: Cast Shadows |
||
| Cast shadow is a great compliment to painting light. Dali is a master of cast shadow and uses it often. |
|
|
|
There are different types of
shadows and a cast shadow is one in which it falls from
an object. A good example of it is when you are walking on
a sunny day and your shadow is tagging along, you wave and it
waves back. A cast shadow is quite different than a shadow that molds the form of an object. Here we are only going to concentrate on the cast shadow.

In this simple line drawing I
outlined a ball and its cast shadow. It's very important that the outer edge of the cast shadow moves back and forward through space, much like an orbit, or it will flatten your image and destroy the light affect. |
|
|
| When I draw a cast shadow, I think in terms of it rotating around an object, as if it's in orbit. |

When shadowing in a cast
shadow. it's important see the middle tones inside of it--those tones
get darker as they get closer to the edge. As you shadow it in, it's also important to differentiate the front and the back of the cast shadow. Here I faded the shadow as it moves back in space. Strong looking cast shadows are the product of direct light. Bright sunlight and artificial light casts them. If your light source is indirect, like on a cloudy day or northern light, the cast shadow will be fuzzy. |

| Here is the same idea, but the surface is folded material. |

|
| Often there are many cast shadows in one painting. Be sure to place all of them in space by differentiating their tonal differences. |

Going back to the Dali, you can see how much advantage he takes using cast shadows. If you are ever using direct light, take full advantage of cast shadows and they will serve you very well. I hope you enjoyed seeing shadows in a fresh light. Michael Newberry
