I started out writing about Squash and Stretch as it applies to drawing and then I realized that I first had to describe what Squash and Stretch means in terms of animation. Of course, it's been covered in a bunch of animation books (and covered well), so most people get all this already, but then again I realized that people use the term "Squash and Stretch" to describe a few different (but similar) concepts.
I'm going to start at the very beginning and try to be exhaustive. There may be readers who are totally new to this concept! So let me try to start at square one, just for fun...
One of the first concepts you hear about when you're studying
animation is "squash and stretch", which is the idea that living forms
(and certain types of inanimate objects) have a certain amount of
flexibility and that they change shape as they move around under their own power, react to
external forces or change expression.
bouncing rubber ball is, of course, the first thing most people
approach as an animation test to learn about squash and stretch.
Without requiring any complicated drawing, it illustrates how a soft
mass can stretch out when it's affected by gravity and squash down when
it comes into contact with a hard surface.
you learn how to apply this to living forms. As people move from place
to place and perform actions, their bodies, limbs, even their clothes
and hair (and everything else) are affected by the forces exerted by the
muscles working against gravity, wind and air resistance, and this is
expressed by drawing the forms squashed down or stretched out. Also,
bodies can squash or stretch if they're affected by external
forces out of their control (like a person tripping and falling face
first on the sidewalk...their face might very well squash into the hard
there's the more subtle affect of squash and stretch to emphasize an
attitude....a character sitting down on a stool, dejected, can sound
like a straighforward and static pose, but using a little extra "squash"
in the drawing can make him feel like gravity is affecting him more
than usual and he has an extra heavy weight on his shoulders...whatever
he's depressed about, it's almost like it's physically pressing down on
him. Conversely, if he has an attitude change and suddenly brightens up,
you might use some stretch in your drawing to show him perking up and
escaping gravity a bit. He's lighter on his toes than usual because he's
suddenly thought of something that lifts his spirits - a way out of the
problem that was troubling him (and squashing him down) a moment before.
third way I think squash and stretch is really important in animation
is to show emotions and thought. There wouldn't be any acting in animation at all without squash and
stretch. Squash and Stretch is the only way, really, to show a change of attitude on a character's face and body to show that they're thinking and processing ideas and emotions. When you go from a Squash to a Stretch, or vice versa, you see a clear change of attitude that shows a change is happening within the character's mind.
This last one is one that I find people under utilize in storyboarding, to be honest. If you ever find yourself storyboarding a sequence (or animating one, for that matter) and the viewer isn't quite connecting with the character, and isn't totally clear on what's going on inside the character's mind - what they are feeling and thinking - maybe you're not using the shifts in Squash and Stretch properly to clue the viewer in to what emotional changes the character is going through.
It doesn't have to be an extreme change. Even very subtle shifts of a Squash to a Stretch (or vice versa) can say volumes. We all have seen an actor (or animated character) lift an eyebrow, or purse their lips, or just slump their shoulders, and immediately with that subtle change you know exactly what that character is thinking and feeling and it's more powerful than any more extreme change would be.
Anyway, more to come next time.....
