iPhone 4S Camera Basics for Seniors

By Nancy C. Muir from iPhone 4S For Seniors For Dummies

iPhone 4S has front- and back-facing cameras. You can use the cameras to take still photos or shoot videos. Take a quick look at your camera by tapping the Camera app icon on the Home screen. The app opens.

You can use the controls on the screen to

Switch between the front and rear cameras.
Change from still-camera to video-camera operation by using the Camera/Video slider.
Take a picture or start recording a video.
Turn on a grid to help you autofocus on still photo subjects.
Turn HDR (high dynamic range for better contrast) on or off.
Tap the Flash button to set flash to On, Off, or Auto.
Open previously captured images or videos.

When you view a photo or video, you can use an iPhone feature to send the image via a tweet or e-mail, print images, use a still photo as wallpaper or assign it to represent a contact, or run a slideshow or edit a video.
