A quick iPhone snap of my wife and best friend at lunch. Not a technically perfect picture, but that's not the point of this shot.
I think I used Camera+ for this one. I like that app for its ability to split focus point and exposure metering. The downside is that you've got to manually export to your photo folder. That's nice in a way, because I tend to sort photos when choosing which to edit. I have less repetition in my folder and can quickly select a photo I'm looking for later.
