I could use some tips for photographing dolphins. I don't really have much experience taking pictures from boats, and most dolphin watch tours offered in Texas coastal towns are very short, so there's not much time to get photos. Also, the water in Galveston (currently the only coastal place I can go to consistently, much to my dismay) is like liquid garbage so it's hard to see the dolphins coming up to the surface. Anyone have any good photography tips for dolphin watch tours? My newest camera has burst mode and I plan to make use of that next time. Anything else I should consider?
