Canon: Accurate Zone AF
As you can see, I was able to get the face in focus through the reeds across the pond. Here's is the crop.
I'm not using the Single Point AF or the Spot AF, I'm using the Zone AF. The Zone AF behaves like the full 19 Points AF but on a smaller area. The closest item within the zone will be in focus. Obviously, not this time.
Q: How did the face get in focus, when it's behind all the reeds and I'm using the Zone AF?
A: It's not just the closest object/subject within the zone that gets in focus, it's the one with contrast that is the closest.
The face is bright, the hood is black and makes a very good contrast, so I didn't have to either switch to Spot AF or focus on the video camera and recompose.
When I took the photo, I didn't see the serenity on his face, I just saw his posture and how relaxed he was.
- He is watching a Sandhill Crane nesting and waiting for the other Crane to take its turn.
- He knows that nothing will be happening soon, it takes a while for the crane to cross the pond, and to take its position on the nest.
