The iMac has a small built-in iSight camera that shoots pictures and videos. It is located at the center top of the iMac screen, making it convenient for taking a quick picture to send someone, shoot videos or to engage in a video chat while you sit in front of the computer. The iSight camera saves pictures in the JPG format, and it has a microphone to record sound when shooting video.
