There have been a number of problems reported about Apple’s iPhone 5 and iOS 6 over the last few weeks, one of those is an issue with the camera on the iPhone 5 that causes photos to produce a purplish haze when there is bright light in the photo.
Apple has now responded to the complaints, and has said that this issue affects most small cameras, including every generation of the iPhone, you can see the full statement from Apple below.
A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture.
Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect.
So there is Apple’s answer to the solution, although a number of sites have compared other smartphones to Apple’s iPhone 5, including previous versions of the iPhone and the issue seems to be much more apparent in the iPhone 5.
