S.D.I. Underwater Photography Instructor

This is the book I did the research for. I went to M.I.T., scoured Dudley's laboratory notebooks, filed some Freedom of Information Act Requests, and interviewed dozens of former colleagues. It was very enjoyable, and, fascinating, three years full-time research.

Because I normally only write technical reports, Douglas and I teamed up with Iain Dey to write this 100% factual scientific thriller / mystery history in a fascinating way that does not require any knowledge of physics or electronics. The book is to be released in U.S.A. October 16, but you can order now.

Be sure to carry your book and a pen around with you so that when you run into me I can autograph it for you. We will be scheduling signing events so that you can get autographs from Iain and Douglas as well.

Underwater Photography Instruction:

Next Underwater Photographer
class starts February 9.

Calendar at bottom of page.  Class in Boca Raton, Florida.

Are you interested in underwater photography?  Do not know where to start?  Perhaps you already have a modest camera system and feel you are not using it to its full potential.  Perhaps you wish to learn more to prepare you to make better decisions before buying more underwater photography equipment.

You do not have to 'spend a fortune' to get pleasing results.  Even with modest 'point-and-shoot' camera, you can learn to take better photos.

Our course is intended for divers that are completely new to underwater photography and those that have some experience with u.w. photography but are not pleased with their results.

Our course includes a minimum of 14 hours of classroom time and two underwater photography dives.  Upon completion of the course you will receive the SDI Underwater Photographer certification.   Our course will alternate between the classroom and the underwater world so that you may learn in increments, practice what you have learned, and then receive personal critiquing and tips for those shots you have taken.
