Join David Mattingly for an in-depth discussion in this video Adding cast shadows, part of Digital Matte Painting: 3 Tone.
The next property of light we want to talk about is cast shadows.…What are cast shadows?…Cast shadows occur when an object blocks the light…that would otherwise be received by an object behind it.…An obvious example on this castle is this doorway…that projects out from the face of the castle.…It is blocking the light that would…otherwise be projected onto this wall behind it.…Let's go ahead and add that cast shadow.…Remember when we started this section, I asked you…to draw in the angle of the sun for reference.…
Here's where we're going to use that.…Refer to the angle of the sun, and that…is the angle that will be projected onto this wall.…You can do a technically perfect projection of this shadow…by plotting the exact position of the sun and using some…fairly advanced perspective.…However, most artists I know fake their cast shadows, and don't do…a technical plot of them, and that's what we're going to do here.…As long as you're consistent in the angle and length of…your shadows faking them will give you a very convincing result.…
