Use Burst Mode for Fast Action Shots
Burst mode lets you capture those fast paced shots, such as children playing, pets running or sporting events. iPhone: Tap and hold the shutter button for as long as you need. You will see the photo count indicator go up. When you are done, let go of the shutter button and the images will be saved and shown as a thumbnail. You can then go through them and select the ones you want to keep.
