Bob Hahn has been a professional photographer for more than 35 years, specializing in corporate, industrial, travel and leisure and underwater photography for print and electronic publications.

My interest in scuba diving started in 2003 and takes me to the Caribbean, Florida, Northeast US and my home area Dutch Springs in Pennsylvania where I teach underwater photography. I am a PADI Master Staff Instructor and teach many PADI specialties including the PADI Digital Underwater Photographer Specialty Course. I am an Olympus certified underwater photography instructor.

I also teach a course in Digital Asset Management and Digital Image Workflow. Information can be found at http://www.underwaterphotoclasses.com , click on Other Courses in the menu. For scuba diving classes please visit http://www.scubadivingclasses.net
