Book Description
Designed for photographers who already have strong diving skills and understand basic photographic techniques, this reference defines what advanced underwater photography is while teaching the skills necessary to create professional-quality images. Opening with a quick overview of the basics—such as exposure, focus, subject selection, and composition—the author then expands on each of these topics, showing the techniques pros use to achieve truly stunning images. A major factor in advancing beyond the basic level of underwater photography is moving from a point-and-shoot or semi-adjustable camera to using a full-featured digital SLR camera. The myriad equipment choices available when making this transition—including cameras, lenses, underwater housings, and the lighting units designed to be used with them—are explained, as are their respective advantages and shortcomings. Because both beginning and advanced underwater photographers can have equipment-related issues, a trouble-shooting section is included to ensure that minor equipment problems won’t ruin a costly dive trip.

Book Description
Simplifying the seemingly difficult and expensive art of underwater photography, this accessible investigation outlines the four elements of success: focus, exposure, composition, and subject. Beginning with an overview of necessary diving skills, this survey reviews these four categories in detail, depicting how to obtain superior results even without the latest and greatest equipment. Maintenance and first-aid tactics are presented as well, reducing the chance of disappointing malfunctions during a dive. Also covered is the importance of developing a photography plan beforehand—both for the safety of the divers and the protection of the underwater environment. Concluding with post-shoot techniques for choosing the best frames, cropping photos for printing, and the top methods of presentation, this examination demonstrates how underwater images can be used to share the world of diving while promoting important conservation efforts.

Book Description
A system based on the time-varying intensity (TVI) approach was built in the early 1970's at the Scripps Visibility Laboratory and experimental data collected by this prototype system showed an imaging capability of between 15 and 20 attenuation lengths at 640 nm. Researchers at the Naval Air Systems Command have developed an updated version of this original system with state-of-the-art components. This new TVI system uses a modulated laser illuminator to convey information about the scan to the distant receiver instead of using a separate optical trigger as was used in the original system. Laboratory water tank experiments were conducted with a prototype modulated TVI system to evaluate the effect of system and environmental variables on the system performance. In parallel with the experiments, an interactive computer simulation was developed to help evaluate the effect of the many variables on the TVI performance. Results from experiments and simulations will be discussed and compared.
