Camera of iPhone 3Gs

The iPhone 3G S's built-in camera is better than what you found on previous iPhone models. It's got three megapixels of resolution, up from two megapixels in previous models. And this camera has the ability to auto-focus. Apple also says that the quality of the images it takes are generally better than the previous model, including vibrant colors and better low-light performance, and that the camera can shoot much faster than the one on previous iPhones. If you've used the camera on the existing iPhones, you know that's setting the bar pretty low.

A cool new software feature in the Camera app is "tap to focus," which lets you select what the camera focuses on. By default, the camera focuses on whatever object is in the center of the display, but if you'd like to focus elsewhere--say, an object in the background--just tap on the object on your iPhone's display. The camera not only changes the focus but also adjusts the exposure and white balance, as well. The camera also includes an auto-macro mode, allowing you to get very close to the objects you're shooting--a major failing of previous iPhone cameras.
