If you did miss, some iPhone users have complained about a purple haze on photo or video with iPhone 5’s camera. It appears to be hardware problem and here is the official respond by Apple:
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.
Of course Apple acknowledges the problem but seem like there is no solution at all. The company even claimed that this problem happens with all iPhone but so far we only have heard on iPhone 5.
Now the solution to get rid of the purple haze is to get less expose to bright light.
