A purple halo seems to be the latest glitch affecting some iPhone 5 owners. Detailed by forum users at tech review site AnandTech, the flaw reportedly occurs on photographs if you aim your iPhone 5 camera toward a bright light source such as the sun or an incandescent light. If you then move the camera so the light source is off screen, a purple halo effect can be seen through the camera. That effect also shows up on any pictures that are taken.

All the shots were taken on the full 8 megapixels offered by each phone, with all other settings set to automatic, All the example images below can be clicked on to view the full-sized versions, All three phones did an admirable job of tackling this outdoor scene, It's not an easy one to capture, as it combines dark areas in the buildings on the left and bright skies surrounding London's Shard, The difficulty in properly exposing was particularly noticeable on the HTC One X and to a lesser extent on the Galaxy S3, Both cameras produced quite strongly blown-out highlights in the sky and the S3's attempt, in particular, resulted in moshi sensecover iphone x smart case - metro black a rather cold colour cast to the scene..
The iPhone 5, meanwhile, gave a much more even exposure overall, avoiding the blown-out clouds, while retaining plenty of detail in the buildings and pavement. Winner: iPhone 5. If the scene you're shooting has a strong mix of bright and dark areas and your phone can't accurately expose by itself, then try setting it to HDR mode. HDR stands for high dynamic range and combines multiple photos, each taken to expose for the bright and dark areas, which are then combined to create an even exposure overall. At least that's the theory.
All three phones offer HDR functions but the results vary considerably, I tested them using the same outdoor scene as before for easy comparison, The HTC One X's approach appeared overly processed, which resulted in a very unrealistic -- and unimpressive -- photo, The Galaxy S3's was much better, with the previously blown-out highlights in the sky rescued, but moshi sensecover iphone x smart case - metro black the overall scene looking a little dull, The once white, fluffy clouds appear like a grey splodge on the skyline, The iPhone 5 maintained the even exposure it captured without HDR, but managed to brighten up the pavement, bringing out some of the detail in brickwork and on the surrounding buildings, It also provided richer colours than the S3 and the One X, So the iPhone takes the top spot in this category..
The iPhone 5 gave the worst performance overall. Its photo lacked detail and clarity. A large amount of image noise also crept in, which is particularly evident on the white walls. The Galaxy S3 came second in this round, providing a sharper, cleaner image than the iPhone 5, although it again suffered from a rather cold colour cast. The HTC One X put in the best performance, with its photo not only sharper than the others but also displaying much less image noise. It produced warmer tones than the S3.
