Congratulations on your certification. Before getting too serious about u/w photo you need to be very comfortable diving & have excellent buoyancy control skills. Some develop quickly, some take a bit longer to master the skills. U/w photo turns into serious multi-tasking. Most of your time is spent on looking for & photographing subjects (adjusting camera & strobe settings, positioning, etc). Diving skills must become second nature. One hand for camera, one hand for diving. And you will become a solo diver at some point (if not most of the time). So - with all this in mind, what's your budget? Will you need a complete setup - housing, ports, lenses, strobes, arms, etc. Is your computer big enough & fast enough to handle files, Photoshop, backup, etc? Laptop for travel? As you can see $$$ can mount up fast. Not to discourage you at all - just making sure that you understand all that u/w photo requires. You DO have a Platinum Card, right? You will see a lot more critters in the sea as a photographer than just a basic scuba diver. Good luck!
