This time around, Apple opted to stick with 8 MP resolution for the iSight camera, but increased the active pixel array area by 15%. Bigger pixels and a wider f/2.2 aperture means the system delivers a 33% increase in light sensitivity.

That's gravy and all, but ever wonder what a 1.5 µm pixel pitch actually looks like? Well wonder no more! The first image in this step shows how your camera sees you when you take that duck-faced selfie.

The end result from these tweaks should be better low-light photography, and combined with the dual-color LED flash, retention of natural coloring. No more Predator-vision party pics. Well... unless you're the Predator.
