Picturing the underwater world

Helen Scales

One of the biggest problems when it comes to caring for the ocean realm is that it is out of sight and out of mind. It's hard to care about something you don't know about, and most people, most of the time, don't have a chance to see ocean life for themselves. Underwater photography is helping to bridge that gap between people and the oceans. In this special podcast, Helen Scales chats to National Geographic photographer Brian Skerry to find out about the challenges of taking pictures underwater, from the technical constraints of taking electrical equipment into salty water to finding ways of portraying both the beauty of ocean wildlife and also the problems it faces today.
