The challenge of recognising and understanding what you see when you look underwater using a snorkel or diving has been with us for many years. Bob in his work with divers when he was with the Marine Conservation Society helped develop a whole series colour photographic guides of the marine species around the UK. The development of whole range of modern digital media now enables this challenge to be addressed at a completely different level.
