This picture was taken outside my home on 06/25/07. I love taking pictures of hummingbirds, I feed them all summer long.
I wanted to capture the hummingbird wings in the picture so I used 4000 ISO.
Hummingbirds wings can beat at up to an incredible 80 beats per second (depending on the species), and it's this speed that makes them "hum".
This also poses a problem for photographers - how to freeze those rapidly moving wings?
The secret is to use a fast shutter speed - in this case, something measured in thousandths of seconds.
This means the photographer needs to set a wide aperture, and as Jill has done here, a high ISO.
The wide aperture has the added benefit of throwing the background out of focus - this concentrates the viewer on the sharp in-focus bird in the foreground.

The shot looks good, if a little small! Any chance of submitting a larger shot, Jill? (no more than 800x600 pixels though).
The only thing that might be worth a try would be to crop out some of the area to the left of the hummingbird.
Leave the space to the right though, as this is the direction the bird is pointing in. If you crop this side the bird will look as though it is "running out of space" in the frame.
