You can upload the photos and videos you take with Camera to photo applications on your computer, such as iPhoto on a Mac.
Connect iPhone to your computer.
Mac: Select the photos you want and click the Import or Download button in iPhoto or other supported photo application on your computer.
PC: Follow the instructions that came with your camera or photo application.
If you delete the photos and videos from iPhone when you upload them to your computer, they’re removed from the Camera Roll album. You can use the iTunes Photos setup pane to sync photos and videos (Mac only, iTunes 9 or later required) back to the Photos application on iPhone. See iPhone Settings Panes in iTunes.
