If you like shooting photos with the iPhone’s camera, but miss the advanced controls from your dedicated camera, you’ll love iOS 8. The new Camera APIs in iOS 8 let developers give you control over camera focus, white balance, and exposure settings.
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 bracketing.
The exposure, or amount of light in a photo, is a factor of three parameters, ISO, shutter speed and aperture. Shutter speed is the amount of time the shutter remains open and can absorb light, ISO rating refers to the sensitivity of the lens, and aperture is the size of the opening of the lens.
Having control over these factors would let advanced photographers click better photos, as they’ll easily be able to adjust exposure settings to increase brightness, reduce noise or minimise motion blur. Control over shutter speed would let photographers take long exposure photos, which results in such images:
Other parameters like camera focus and white balance can also be set manually, letting users create photos and videos that could only be shot using dedicated cameras.
The App Store currently has a wide range of photo filter, photo editing and camera apps. These new changes in iOS 8 would not only let these apps improve their functionality, but also create opportunities for all-new apps to let users tap into these new controls, even if they don’t have a lot of theoretical knowledge about photography, and create great photos and videos.[via Anandtech]
