and it's got an incredible grand scale.

So it's very difficult to try and capture it with images.

Being a National Geographic photographer

creates an opportunity for me to document the world

and you don't know what you're going to uncover.

You are going into the unknown.

There's always a bit of nervous excitement.

To get to Antarctica we have to get across one of the

most treacherous crossings on the planet

which is the Drake Passage.

Antarctica is other-worldly.

Big mountain ranges

and endless seas of ice.

And it's a challenging place to document

because it feels like you can never really do it justice.

I'm trying to showcase this land of extremes.

How every single flake of snow

counts towards building that incredible landscape.

It's strange to think that something so light

can compact over thousands of years

and trap so much history in the glacier.

I like to be as prepared as I can be

but I want to leave myself open to

inspiration from the environment.

So the calving just happened and it's created a wave

and we can see it push up all the ice on to the beach.

There's these kind of beautiful coincidences that happen

and that's when those really special images

tend to eventuate.

I find that the colours in Antarctica

pull you out of yourself.

Yet it is the most present that we get to be.

You can see quite a lot of water pouring out of the glacier

We all know that Antarctica is deeply impacted

by climate change.

And I want to try and showcase that fragility

through the macro and the micro.

You can hear the ice releasing the air bubbles

and it sounds like popcorn.

So we are recording underwater

because most of the iceberg is under the surface

so this is going to give us a bit of a glimpse.

That was on Ultra Steady as well.

It's an electric feeling to

see these images that I have envisioned

and to suddenly see them come to life.

He's collecting all the little rocks

and he's creating a nest.

What I really love, especially with nature, is that

it reveals itself gently and a little bit by bit.

I think a big part of my work is

uncovering those moments.

When I capture an image that I feel like

encapsulates that moment.

It's a feeling of coming home.
