We saw many wonderful features in iOS 8 at WWDC earlier this month. But there are still more.
According to AnandTech, they found a new API in iOS 8 which will give a manual exposure in the iOS 8 native camera app. This can be a very good feature as Apple had "lock" their iOS camera app for the pass many years.
The API will allow developers to release apps that take proper control of things like shutter speed, ISO and EV bracketing and also exposure bias. Besides that, focus and white balance will also be available.
