In this video, we learn how to use the camera on the iPhone 3GS. From the home screen, tap the camera icon. From here, the camera will appear on the screen with what you can take a picture of. At the bottom of the screen you will see the camera icon, thumbnail icon, and photo/video switch icon. You can tap the screen to do a focus and you can tilt the camera sideways to take a landscape portrait. To take a photo, tap the camera icon and then the photo will be saved to the thumbnail. Enjoy using this and have fun!
