If you've been using your iPhone 5 since the start and have never noticed a little bit of the ol' Purple Haze appearing at the edge of your photos, you're lucky - Apple has just addressed this situation occurring with some users in an official statement today. It would appear that if you've got a light source right outside the viewing area of your iPhone 5's camera lens, you get a purple light leak into your final photo product. Apple today has let it be known that users should be pointing cameras away from bright light sources to do away with the oddity altogether.
A public support document has been posted regarding the so-called Purple Halo, as it were, with Apple letting it be known that it's an issue that's known, but not limited to the iPhone. This public support document notes that a light source just outside the field of view of the camera will be best if you actually DO want to get the effect. A slight move of the camera - like actually turn your phone, for real - that'll be the end of it.
"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." - Apple
This support document also has listed symptoms as "A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture." Sound pretty accurate to you, for those of you feeling the light loveliness? Let us know if you've had any issues - and on that note, let us know if you've not noticed this color at all, too.
