Apple has revealed a solution to the so-called purple halo issue on the iPhone 5. The company posted the resolution onto its official support page.
The issue emerged soon after the iPhone 5’s launch, with users noticing a strange purple effect on photos when a strong light source was just off camera.
Some have speculated that it’s the iPhone 5’s new Sapphire lens element causing the purple glow effect. Apple swiftly promised to investigate the issue, and this is what it found.
Interestingly, while Apple acknowledges the purple halo issue exists, it appears to be suggesting that it’s a common quirk with the majority of smartphone cameras. “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” reads the post.
This part of the response reminds us a little of the ‘Antennagate’ debacle, when Apple claimed that a number of the iPhone 4’s key rivals also suffered reception issues when held a certain way.
Apple then goes on to explain the source of the iPhone 5 purple halo problem - kind of. Apparently a strong light source (like the sun) just out of view “causes a reflection off the surfaces inside the camera module and onto the camera sensor.”
Apple’s solution to this problem: “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 you have it. If you’re getting a purple halo effect when taking certain pictures on your iPhone 5, take them from a different angle.
