Is this Peter?

My copy of iPhoto ‘09 arrived this week, and I sat down this morning to take its new facial recognition features, branded Faces, out for a ride. While it’s not perfect, it’s pretty good. You train it for a while — not too long, as it turns out — and then it starts to be able to guess at the identity of faces on its own:

Some observations after an hour of work:

• So far it’s been unable to identify Oliver in any photos, perhaps because he’s growing so fast so he looks different in every photo.
• My father has proved the easiest to consistently identify: he has a distinctive beard, so this isn’t surprising, and I can imagine the only way iPhoto would get confused is if I threw a lot of David Suzuki pictures into the mix.
• I have twin brothers. This is problematic.
