About Camera
With iPhone, you have a great still camera and video camera wherever you go.
iPhone 4 has a main camera that takes photos and high-definition video, an LED flash
for photos and videos taken with the main camera, and a front camera that lets you
make FaceTime video calls and take photos and videos of yourself.
The main camera is on the back of iPhone. You use the screen to control the camera
and to see the photo or video you’re taking. Tap-to-focus lets you tap anywhere on the
screen to focus on a specific object or area of your shot and automatically adjust the
exposure. The macro autofocus feature (about 10 cm) and a 5x digital zoom let you
take great close-ups.
If location services is turned on, photos and videos are tagged with location data—
including your current geographical coordinates provided by GPS, Wi-Fi, or cell-tower
information. You can use location data with some apps and photo-sharing websites
to track and post where you took the photos. For example, the Photos app organizes
photos by places.
Note: If location services is turned off when you open Camera, you may be asked to
turn it on. If you don’t want to include location data with your photos and videos,
you can use Camera without turning on location services. See “Location Services” on
page 194.
