Thanks Tim for this reminder. I'll keep it in mind. I believe it too, and have experienced it myself sometimes too.
However, I do have a personnal vision of, let say, one week on the same spot, with two dives a day.
My last 3 days will be aiming specifics like you describes. But if you want, for example, to write an article about the spot, you might want to use 2-3 days to just be 'productive' in number of good shots. No awesome shots, just technically good, describing the area or subjects. When you have that, you have the skelekon, the scene. And now is the time for your final pieces, your jewels, you personnal touch.
this is generally what happens when you get in a new sea/country you don't really knows. The first dives you'll just come out of the water with 150 technically good shots of everything around.
Then you learn what is common / boring, and to ID the special critters, or to ID the common critter that have the potential for special shots without too much effort.
Then you want to do the effort, you just jump strait under the boat for some macro shots, sit on the sand on the first rocky area you meet, and spend your next 2 hours here
Or go at the same nice seascape location freediving again and again waiting for a shark or a ray to pass by, having set your scene.
Anyway, I need to learn this 'Aim' thing by myself better. It's never enough to just 'know' something, you need to experience it yourself again and again to fully realize it and apply. for now I'm just being productive because I don't dive much (what an irony !?). I'll get serious at doing less when I'll have more time !
Having potentially two set-up doesn't mean you'll do all your dive with. Maybe 1/4 of them will be already a lot !
But Thanks again, I know I will remember all this soon enough ; )
