Soon after the release of the iPhone 5, some users began noticing a purple flare or halo showing up in photos taken with the device's camera pointed at or near bright light sources. The issue is certainly not unique to the iPhone 5, but it has caused concern for some users.

Last week, Gizmodo reported that Apple had responded to address the issue, with Apple's support staff providing an emailed response to a user inquiring about the purple flare. According to Apple's engineers, the issue is indeed normal and users are advised to point their phones away from bright light sources when taking photos.

According to Apple's engineers, the issue is indeed normal and users are advised to point their phones away from bright light sources when taking photos.
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. The purple flare in the
image provided is considered normal behavior for iPhone 5's camera.
Following that private email response regarding the issue, Apple has now posted a public support document recommending similar action to minimize 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 minimize or eliminate the
effect.
The iPhone 5 uses a similar camera to that found in the
iPhone 4S, although Apple reduced the camera's thickness by 20% in order
to fit into the thinner body of the iPhone 5. Apple did, however, add a
several enhancements to the camera in the iPhone 5, moving to a
sapphire lens cover, improved image signal processing and noise
reduction, and a new dynamic low-light mode.
