When I'm shooting basketball, I'm mainly reacting and not creating. The players are moving so fast that there is no time to set things up. I can only guess/anticipate where the action is going by knowing the players and what they like to do; e.g., Kobe Bryant will shot from almost anywhere on the court. Be ready!
The times I've actually "created", I was waiting for several moving subjects to get into the right relationship with each other. While in Monterrey, CA outside the aquarium, I waited for 3 yachts to form a nice triangle in front of a brightly lit hotel in the background. I tried to get all three sailing in the same direction but no luck. At least I got 2 of them going in the same direction and the other in the opposite direction while forming a nicely composed triangle.
The 2nd example was on the 17-Mile Drive. We passed a group of women hiking on the side of the road while driving to a lookout point. At the point, I shot some seascapes and when I looked back I saw a nice shot of the rocky coast, a golf fairway, a HUGE house and the trees behind it. Nice, but I thought the line of women would add to the shot, so I waited about 10 minutes until they were in the right position.
When I'm shooting in my garden, I "create" by getting down to the level of the subject. I rarely shoot standing straight up unless the background I need can only be had standing straight up. On my knees a lot, and sometimes laying on my stomach. I have a right-angle viewfinder which I'm using more and more.
Too much stuff, not enough shooting time.
