Many developers and users have been frustrated with the lack of control when it comes to iPhone cameras. That is due in part to the kind of control that Apple likes to have, although they seem to be giving up a bit of that.
iOS 8 is going to bring a lot of different changes, but what is important here is the fact that the camera API will be released and allow many new features to be controlled in third party Apps. Among the things that will now be capable of changing are the ISO sensitivity, the shutter speed, the white balance, the exposure, and the focus. That means there will be a great deal amount of flexibility available for the first time. Aperture is fixed in mobile devices, though, so it won’t be changed.
For photographers, this is a huge upgrade. The iPhone has a great camera that is capable of taking high quality pictures, although the lack of support for making manual changes has held many people back from using it to the full extent. This does still leave one thing out, though, and that is the access to raw photos. For professionals, that is still something that will hold them back, but for the vast majority of people it won’t be a problem.
This is certainly going to be an exciting upgrade, although it isn’t all that will be coming in iOS 8. It is expected that it is going to be released alongside the new iPhone 6, which will bring its own host of new features.
