I love the newer versions of iPhoto for many reasons, one of them being the face recognition feature. Just tag a photo with a person's name and highlight their face, and iPhoto neatly organizes all the photos with them in it. Perfect for when you need to find a specific shot or you want to rag on a certain someone for all those late-night debauchery pics you've collected over the years.
But when I was organizing photos of my family over the weekend, I ran into a little problem when iPhoto tried to recognize my game-loving grandpa as you can see in this screenshot. How can a sweet-faced senior be mistaken for a Mr. Potatohead tattoo? Mistake one senior for another, sure, but not for a sharpie-drawn pic on my forearm. I thought it was pretty hilarious, and if you're wondering about the tat, don't. It was Halloween 2006. 'Nuff said.
Buuut, I can't hate on iPhoto for too long, since it comes packed with some other amazing features as well. To find out what they are, just read more.
Besides iPhoto's (sometimes wonky) facial-recognition ability, with the help of a GPS enabled camera (or your iPhone's camera), your pics can be organized by location, and you can check them out on a map. Kinda like Flickrvision, but without having to tag all the photos yourself. Plus, if you're into sharing, you can upload your snapshots right to Facebook and Flickr without having to leave iPhoto. I think it's pretty sweet, even after the Mr. Potatohead incident.
