Ice Cream Sandwich offers significant upgrades to the OS's Camera app, including continuous focus and zero shutter lag exposure. Google also pumped up the shutter control speed, so you can shoot one photo after the next with no delay between shots. You'll also be able to take quick screen grabs of videos--even those recorded at full video resolution--by tapping the screen as the video records.
A new face detection feature will automatically locate faces in your shot and focus in on them. You can also use the new tap-to-focus option to zoom in on any part of the frame you'd like by tapping the location on your screen.
One of the best enhancements to the Camera app is the single-motion panorama mode. Using this option you can capture a large panoramic image by moving the camera slowly from left to right in front of you. New photo editing options let you quickly remove red-eye, crop, rotate, and add effects to your images.
