Review: iPhone 3G
Rich noticed a few things about the images captured by the iPhone's camera. The orientation is not set when photo files are created from the camera. Instead, orientation is attached at meta-data, so it's only right-side up in some apps, like iPhoto or Preview. File thumbnail in Finder is oriented the wrong way, and it's the same if the photo file is moved to Windows.
Images taken in daylight can look fantastic. I've also had amazing luck in some low-light situations, such as concerts. Dark bars, on the other hand, prove to be too much, especially since the iPhone does not have a flash. Images can be nearly unusable.
Overall, though, the iPhone's camera does better than many other 2MP cameras.
