After privately telling an iPhone 5 user that the purple halo sometimes produced by the device's camera was due to how they were framing photos, Apple has gone public with suggestions for preventing the flare on images.

Soon after the device went on sale last month, owners began complaining of a purple colour showing up on the edges of photos, an issue that typically occurs when a light source is immediately nearby, though it can occur even when the light is off frame. It can also affect both photos and videos.
Earlier this month, an AppleCare support representative responding to an iPhone 5 owner's complaint about the issue, said the purple flare was "considered normal behaviour" for the devices camera and further explained that, "Our engineering team just gave me this information, and we recommend that you angle the camera away from the bright light source when taking pictures".
Now, the iPhone maker has followed up by posting a public support document that recommends similar action to combat the issue:
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 minimise or eliminate the effect.
