One way the small army of engineers has made family photos better is by building a way to counteract people's shaky hands. 

Inside the camera are four tiny wires, each half the width of a human hair. The four wires create a "microsuspension" of the camera parts that can absorb the shaking from hands to get a steady shot. 

Townsend's team also has its own lab to test how the camera photographs in different lighting situations. The engineers have to calibrate the camera to take the best shot, whether it's the bright light of high noon over the camera or the yellow-ish dim of sunset.
