As you may know, when you take a photo with HDR enabled, the iPhone takes 3 photos in rapid succession. It takes one that's in normal exposure, one that's underexposed and one that's overexposed. The iPhone combines these 3 photos with its own algorithm to produce an HDR photo. Now, when I take an HDR photo with my iPhone 4 running iOS 5.1.1, most of the time, there aren't any problems. However, the HDR photos sometimes aren't combined correctly, especially when taking photos of grids, straight lines, etc. (The size of the photos below were reduced. Annotation was added and GPS information was removed. No other changes were made.) Do you have this issue as well or do you think it's a software issue which will be fixed in iOS 6? Thanks in advance.
