I'd like this thread to explore pictures with an emphasis on focus (or lack thereof) as a tool. Share your images where you used focus to highlight or emphasize some aspect of the composition.
Starting with this agave, which I've taken dozens of pictures of. Can't help myself, it's so photogenic.
But rather than go for the view from above, with full radial symmetry and even focus, I took this picture from the side, knowing that part of the image would be out of focus. By focusing on the central bud, I tried to create a sense of origin, and the out-of-focus parts almost seem like they are in motion (to my deteriorating eyesight and overactive imagination, anyway).
Now I'm a total amateur at photography, as I suppose is evident from the results of my little experiment. So I'd love to see some more expert pictures from y'all, with a couple sentences of explanation about how you used focus to make them more interesting.
