To be clear, iOS 8 will expose just about every manual camera
control possible. This means that ISO, shutter speed, focus, white
balance, and exposure bias can be manually set within a custom
camera application. Outside of these manual controls, Apple has
also added gray card functionality to bypass the auto white
balance mechanism and both EV bracketing and shutter speed/ISO
I’ve said it before and will say it again: Apple has become one of the leading camera companies in the world, and quite possibly the most innovative. The image quality from the iPhone camera is an ideal example of hardware and software being inextricably tied in Apple products.
