It is exciting for new underwater photographers to take their first step in this direction. The excitement comes not only from the very idea of capturing an underwater scene on film, but also from being in a completely-different environment that they are not used to. Now that a photographer is in a different enviornment, the fundamentals of photography still remain the same wherever you are taking pictures, but when the medium that light travels through is water - not air - special techniques and equipment are needed in order to capture good images.
