Whenever I've been away, either travelling or for work, I've sent Sound Postcards to family and friends. I find the combination of a still image with audio to be more moving than a quick video. A bit like audio books, part of the work is done for you but you still need to use your imagination to build the full picture, and I think that stays with you for longer.

Sound is almost always coupled with moving images, but photos allow you to keep the auditory sense at centre stage. Something we're always aiming for!

Parque Nacional Los Glaciares, 1/6/2010

Dear May,

It's early in the morning and I finally made it to this amazing corner of Patagonia. I tried getting inside the park in the middle of the night to beat the crowds but the guards wouldn't let me so I set camp in front of the gate and waited anxiously between snoozes, like it was the first day of sales at El Corte Inglés.

I managed to wake up on time and still be the first car in so got a good hour one-to-one with Perito Moreno. And the wait was all worth it as the monstrous glacier offered itself up in full; rips, cracks, booms and splashes continuously animating the morning. You know Perito Moreno is one of the few glaciers in the world that isn't receeding?

Thank you Perito, thank you Patagonia. Hope you enjoy it as much as I did. One day, we'll go back together.

Love,
A.
