This is all well and good as an "in the meantime" fix. However, if TH's original assessment of the situation is correct ("It's an issue with iOS8"), then you/we are still waiting on Apple to fix the underlying issue.
With iOS 8.1 released, I didn't see anything in the fix log pertaining to algorithm corrections in the camera app.
One 'quirk' that has no work-around - lack of storage. Without swappable storage, this ticks one of my no-go boxes. Hope that the Xperia z4 or the Galaxy s6 put out some great numbers. Or, that M$ will learn from other's mistakes and add removable storage and a good photo processing partner for some decent imaging software.
