I travelled to Antarctica in December on holidays with my family. I brought along my camera rig to shoot the glaciers, ice and penguins. We saw thousands of icebergs of course, but only one revealed its gorgeous underside -- the 90 per cent "below the surface" you hear so much about.
Icebergs are typically white, like you see in pictures. This one had recently flipped over and had this arresting alien-green colour to it. It looked a lot more like a parked spacecraft than a floating iceberg.
I shot these photos from a Zodiac which allowed me to get pretty close. There's always a danger of the iceberg flipping back over, so we couldn't get too close. I had a 16-35mm lens on my Canon 5D Mark II, and the wide angle was versatile enough to capture the hunk of floating ice from any perspective.
From an artistic perspective, they are beautiful photos, but they're mostly striking for what they are, rather than anything I did myself. I was just lucky to be there to snap it. You could have pointed an iPhone at this thing and come away with something spectacular.
