1. A method of using multiple optical chains, said multiple optical chains including at least a first group of optical chains and a second group of optical chains, the method comprising: capturing images using said first group of optical during a first time period; generating a first composite image from images captured during said first time period using said first group of optical chains; capturing images using said second group of optical chains during a second time period, optical chains in said second group of optical chains have a different focal length than optical chains in said first group; and generating a second composite image from images captured during said second time period using said second group of optical chains.
