Change the ISO or shutter speed
camera, iphone, performance
Solution
You unfortunately have very little control over the iPhone camera. You can only lock or unlock the exposure, white balance, and focus modes.
Camera+ actually does not have control over anything you described. It used to be able to as it hacked the hardware, which is naturally a great way to get your app rejected by the reviewers.
I hope that iOS6 will give developers greater control as it is a PITA.
Problem
I am tring to control the ISO and the shutter speed for the iphone, but it has no API in AVFoundation. It can only change the exposure, wb for iphone. How can i control the ISO or shutter speed?
