This is one of the finest examples of underwater photography ever. I'm a diver and have visited some of these places, and this will give anyone a first hand look at what goes on underwater. The colors are true and the sounds are incredible. I'm very glad to have been able to see it. I'm told that the IMAX cameras weigh in at 1500 pounds. Even underwater with neutral buoyancy, moving those cameras about must have been a real challenge. The narrators do a wonderful job of keeping the film interesting for non divers by questioning each other, and then answering those questions in a revealing manner. This film is suitable for grade school children through adults. A great endeavor.
