When I was seven years old,
some well-meaning adult asked me what I wanted to be when I grew up.
Proudly, I said: "An artist."
"No, you don't," he said,
"You can't make a living being an artist!"
My little seven-year-old Picasso dreams were crushed.
But I gathered myself,
went off in search of a new dream,
eventually settling on being a scientist,
perhaps something like the next Albert Einstein.
I have always loved math and science,
later, coding.
And so I decided to study computer programming in college.
In my junior year,
my computer graphics professor showed us these wonderful short films.
It was the first computer animation any of us had ever seen.
I watched these films in wonder, transfixed,
fireworks going off in my head,
thinking, "That is what I want to do with my life."
The idea that all the math, science and code I had been learning
could come together to create these worlds and characters
and stories I connected with,
was pure magic for me.
Just two years later, I started working
at the place that made those films, Pixar Animation Studios.
It was here I learned how we actually execute those films.
To create our movies,
we create a three-dimensional world inside the computer.
We start with a point that makes a line that makes a face
that creates characters,
or trees and rocks that eventually become a forest.
And because it's a three-dimensional world,
we can move a camera around inside that world.
I was fascinated by all of it.
But then I got my first taste of lighting.
Lighting in practice is placing lights inside this three-dimensional world.
I actually have icons of lights I move around in there.
Here you can see I've added a light,
I'm turning on the rough version of lighting in our software,
turn on shadows
and placing the light.
As I place a light,
I think about what it might look like in real life,
but balance that out with what we need artistically and for the story.
So it might look like this at first,
but as we adjust this and move that
in weeks of work,
in rough form it might look like this,
and in final form, like this.
There's this moment in lighting that made me fall utterly in love with it.
It's where we go from this
to this.
It's the moment where all the pieces come together,
and suddenly the world comes to life
as if it's an actual place that exists.
This moment never gets old,
especially for that little seven-year-old girl that wanted to be an artist.
As I learned to light,
I learned about using light to help tell story,
to set the time of day,
to create the mood,
to guide the audience's eye,
how to make a character look appealing
or stand out in a busy set.
Did you see WALL-E?
There he is.
As you can see,
we can create any world that we want inside the computer.
We can make a world with monsters,
with robots that fall in love,
we can even make pigs fly.
While this is an incredible thing,
this untethered artistic freedom,
it can create chaos.
It can create unbelievable worlds,
unbelievable movement,
things that are jarring to the audience.
So to combat this, we tether ourselves with science.
We use science and the world we know
as a backbone,
to ground ourselves in something relatable and recognizable.
"Finding Nemo" is an excellent example of this.
A major portion of the movie takes place underwater.
But how do you make it look underwater?
In early research and development,
we took a clip of underwater footage and recreated it in the computer.
Then we broke it back down
to see which elements make up that underwater look.
One of the most critical elements
was how the light travels through the water.
So we coded up a light that mimics this physics --
first, the visibility of the water,
and then what happens with the color.
Objects close to the eye have their full, rich colors.
As light travels deeper into the water,
we lose the red wavelengths,
then the green wavelengths,
leaving us with blue at the far depths.
In this clip you can see two other important elements.
The first is the surge and swell,
or the invisible underwater current
that pushes the bits of particulate around in the water.
The second is the caustics.
These are the ribbons of light,
like you might see on the bottom of a pool,
that are created when the sun bends through the crests
of the ripples and waves on the ocean's surface.
Here we have the fog beams.
These give us color depth cues,
but also tells which direction is up
in shots where we don't see the water surface.
The other really cool thing you can see here
is that we lit that particulate only with the caustics,
so that as it goes in and out of those ribbons of light,
it appears and disappears,
lending a subtle, magical sparkle to the underwater.
You can see how we're using the science
the physics of water, light and movement
to tether that artistic freedom.
But we are not beholden to it.
We considered each of these elements
and which ones had to be scientifically accurate
and which ones we could push and pull to suit the story and the mood.
We realized early on that color was one we had some leeway with.
So here's a traditionally colored underwater scene.
But here, we can take Sydney Harbor and push it fairly green
to suit the sad mood of what's happening.
In this scene, it's really important we see deep into the underwater,
so we understand what the East Australian Current is,
that the turtles are diving into and going on this roller coaster ride.
So we pushed the visibility of the water
well past anything you would ever see in real life.
Because in the end,
we are not trying to recreate the scientifically correct real world,
we're trying to create a believable world,
one the audience can immerse themselves in to experience the story.
We use science to create something wonderful.
We use story and artistic touch to get us to a place of wonder.
This guy, WALL-E, is a great example of that.
He finds beauty in the simplest things.
But when he came in to lighting, we knew we had a big problem.
We got so geeked-out on making WALL-E this convincing robot,
that we made his binoculars practically optically perfect.
His binoculars are one of the most critical acting devices he has.
He doesn't have a face or even traditional dialogue, for that matter.
So the animators were heavily dependent on the binoculars
to sell his acting and emotions.
We started lighting and we realized
the triple lenses inside his binoculars were a mess of reflections.
He was starting to look glassy-eyed.
Now, glassy-eyed is a fundamentally awful thing
when you are trying to convince an audience
that a robot has a personality and he's capable of falling in love.
So we went to work on these optically perfect binoculars,
trying to find a solution that would maintain his true robot materials
but solve this reflection problem.
So we started with the lenses.
Here's the flat-front lens,
we have a concave lens
and a convex lens.
And here you see all three together,
showing us all these reflections.
We tried turning them down,
we tried blocking them,
nothing was working.
You can see here,
sometimes we needed something specific reflected in his eyes
usually Eve.
So we couldn't just use some faked abstract image on the lenses.
So here we have Eve on the first lens,
we put Eve on the second lens,
it's not working.
We turn it down,
it's still not working.
And then we have our eureka moment.
We add a light to WALL-E that accidentally leaks into his eyes.
You can see it light up these gray aperture blades.
Suddenly, those aperture blades are poking through that reflection
the way nothing else has.
Now we recognize WALL-E as having an eye.
As humans we have the white of our eye,
the colored iris
and the black pupil.
Now WALL-E has the black of an eye,
the gray aperture blades
and the black pupil.
Suddenly, WALL-E feels like he has a soul,
like there's a character with emotion inside.
Later in the movie towards the end,
WALL-E loses his personality,
essentially going dead.
This is the perfect time to bring back that glassy-eyed look.
In the next scene, WALL-E comes back to life.
We bring that light back to bring the aperture blades back,
and he returns to that sweet, soulful robot we've come to love.

Danielle Feinberg: There's a beauty in these unexpected moments
when you find the key to unlocking a robot's soul,
the moment when you discover what you want to do with your life.
The jellyfish in "Finding Nemo" was one of those moments for me.
There are scenes in every movie that struggle to come together.
This was one of those scenes.
The director had a vision for this scene
based on some wonderful footage of jellyfish in the South Pacific.
As we went along,
we were floundering.
The reviews with the director
turned from the normal look-and-feel conversation
into more and more questions about numbers and percentages.
Maybe because unlike normal,
we were basing it on something in real life,
or maybe just because we had lost our way.
But it had become about using our brain without our eyes,
the science without the art.
That scientific tether was strangling the scene.
But even through all the frustrations,
I still believed it could be beautiful.
So when it came in to lighting,
I dug in.
As I worked to balance the blues and the pinks,
the caustics dancing on the jellyfish bells,
the undulating fog beams,
something promising began to appear.
I came in one morning and checked the previous night's work.
And I got excited.
And then I showed it to the lighting director
and she got excited.
Soon, I was showing to the director in a dark room full of 50 people.
In director review,
you hope you might get some nice words,
then you get some notes and fixes, generally.
And then, hopefully, you get a final,
signaling to move on to the next stage.
I gave my intro, and I played the jellyfish scene.
And the director was silent for an uncomfortably long amount of time.
Just long enough for me to think,
"Oh no, this is doomed."
And then he started clapping.
And then the production designer started clapping.
And then the whole room was clapping.
This is the moment that I live for in lighting.
The moment where it all comes together
and we get a world that we can believe in.
We use math, science and code to create these amazing worlds.
We use storytelling and art to bring them to life.
It's this interweaving of art and science
that elevates the world to a place of wonder,
a place with soul,
a place we can believe in,
a place where the things you imagine can become real
and a world where a girl suddenly realizes
not only is she a scientist,
but also an artist.
Thank you.
