As part of their new iPhone 4S promotional web pages, Apple has included several full-resolution sample shots for download.
We've included three of the shots here. Clicking on the image will download the full-size 2-3MB 3264x2448 pixel photos to your computer.
Several other examples are available to download at the bottom of Apple's 4S camera page. Of course, these may represent ideal shots, but should give you something to analyze while you wait for the 14th.
