Damo,
It takes some time to get the right situation. First you have to find the beautiful woman who will put up with you and loves the ocean. Helpful hint: require they get certified before you get married and take any prospective life partners diving for a week to find out if your compatible. Must be a great model and be willing to swim in slow circles while you spend half the dive in the same place to get that macro shot. Extra credit if they spend their time finding the next subject to shoot. That should take about ten years to get right, some people find a few cycles of this phase are needed.
Then you have a son or daughter who loves the water and is still speaking to you by the time they are old enough to dive. Teach them to love the ocean and protect all it's creatures. At this stage you now have someone to carry your stuff.
Extra credit if they enjoy photography. (Although more expensive) Double extra credit if you can convince them to get their instructor rating (The resorts and liveaboards will let you dive alone without the herd, which was your original question) This takes about 20 more years so it's good to start early.
Then if your lucky your son (or daughter) will find their someone who loves the ocean and can put up with all of you. Extra credit if they are a computer guru who can make photoshop sing) You are now in the perfect situation. Lots of room in your carry ons, Two full DSLR systems in the water for each dive, one WA and one macro with good divers and reasonable photographers behind each camera. A loving spouse to find subjects, keep you warm at night and will still talk to you after too much rum. And now you have a younger model (your son's partner) to share all the joys of diving with all over again. (If done correctly this repeating cycle of sharing keeps you diving)
Because you've now spent a few thousand hours in the water with your small crew, underwater communication is done by some sort of osmosis. Can't explain it, I just know it works this way. This takes another 10 years, so by this time you really need someone to carry your stuff.
Not an easy route to diving nirvana but I can attest it's possible and well worth all the struggles along the way. By the way, every once in a while it's still great to sneek out on your own and just hang at the top of the reef looking out into the blue, wondering how you got so lucky. B)
