In addition to opening up the aperture as wide as possible, you want
to use the longest zoom possible to minimize the DOF. Get the
subject as close to you as possible while still allowing the desired
framing and allowing the camera to focus, and keep the subject as far
away as possible from the background.

Excellent advice - works well with my Panasonic FZ5 so should work with
the Canon S3 IS too. The subject can end up being quite a distance away,
though, with the 432mm longest zoom!
