Those Funny 25-Year-Old Scars On Dad's Face
Unedited and unenhanced photo, shot with the iPhone 3G S.
The camera on the 3G S has an automatic macro mode that can focus as close as 10 centimeters. And the "tap to focus" feature tells the Camera app which bit of the image should be in focus.
Also a very nice demo of the app's color capabilities. Lots of a single, intense color...but no flares, no blowouts, and accurate hue.
