Now now guys.... let's not fray too far away from astin's initial request of knowing what to do whilst her wife is diving.
Well Astin, to give a good complilation of what has transpired;
Normally there will be 2 types of dive operations 1.) resort based 2.) LOB (abbr for Live on Board)
If for instance, you are going to a resort based operations, then most probably you will have some scenery to photograph, *most* do have beaches, clear blue water...... well most... again it depends which part of the world you are talking about.
If you are on a Live On Board, then you are basically stuck on the boat, again depending on which part of the world you are at, you'll be able to photography some scenic islands, even children on their small bumboats on fishing trips. Most dive sites are quite close to islands, if they have a small bum boat, you'd might want to tell them to drop you off at a nearby island for some scenic pictures. If you are lucky, you'd catch a couple pods of dolphins or whales.
Then again if you are land based/resort based most probably you will have chances of taking photos of bikini clad babes, then again they wouldn't be as prolific as the models you have engaged. Then again there are models that you have engaged, that do dive. All depends on your luck and which resort you are looking at. Certain places are known to have a huge frocliking of japanese divers on certain time of the year, and some places are reknown to have greek and german sun goddess.
Well if you are up to it, there are alot of resort based operations that do provide daily trekking tips to national parks, (if any in the vicinity), else there are always sea sports like jet skiing, wind surfing.. etc assuming you are at a classier dive resort.
If the dive destination that you are visiting is near to a town or a city, then i would presume that you'd be able to visit the city for photographic opportunities.
Hope all there have quenched your query on activities whilst your partner is getting loaded with nitrogen.
A gentle reminder to all, not to sway too far away from the initial thread starter's request. As goondo has pointed out before, this is a Underwater Photography forum.
cheers
