Since the iPhone 5 has been released some users have been complaining about a purple flare phenomenon that affects some of the pictures taken with the new smartphone. The problem is known as “Chromatic Aberration” and is known to cause a purple-colored “flare, haze or spot”. This week, Apple has posted a document in which it explains the root of the problem. They also added a quick fix to sort out the problem.
Cupertino stated that the problem appears in pictures taken with a light source situated outside the frame. The light in question will reflect off the surfaces in the camera module and further on to the camera sensor. That’s how users experience the annoying flare. Apple also says that the problem is not specific to the iPhone 5 but has been seen in the iPhone 4S as well. The solution Apple gives is quite simple. Just try to retake the picture, framing it in a different manner or just shield the camera with an object or your hand in order to remove any side effects.
Since the iPhone 5 launched, Apple has received its fair share of complaints about the product. Some users were concerned the device was fragile and prone to scuffs or scratches. But the issues that got the most attention was the bad quality of the much hyped Apple maps app. CEO Tim Cook even made a public apology for it. Apple probably tried to resolve the camera problem quickly so as not to raise more questions about hardware issues. Nevertheless the explanation given by Cupertino seems one approved by photography experts, and the camera is still considered to be one of the best of any smartphone.
