Advanced Camera Settings - Central Focus Point

For this activity, I experimented with the Central Focus Point on my Canon 550D. This means the camera will focus solely with the central section of the lens.

I used a small owl in good light to take these shots and showed the effects the central focus can have on focusing an image.

Findings:
In this experiment, I found that centre focus is much more precise than the automatic selection option. If you were not very careful about where you wanted to place focus in the image, it would focus on the wrong part of the image.

In image 1, I focused on the beak of the owl, depressed the shutter half way, then moved the camera to include more space to the right, while trying to keep my focus on the owl's beak. It worked well and the owl stayed in good focus.

In images 2 and 3 I used a similar technique but from different angles, again to good effect.

In image 4, I wanted to see what would happen if I allowed the camera to focus where it wanted to after I had moved the camera and it focused on the centre of the tree outside the window in the far background, leaving the owl in obscurity.
