At IFA yesterday, two new smartphones were announced with 8-megapixel cameras. HTC and Lenovo’s devices are joined by Microsoft’s Lumia 730 selfie phone and Sony’s Xperia C3 pro selfie handset in being tailor-made for the auto-photography crowd. Image quality from primary smartphone cameras has plateaued and megapixel counts long ago surpassed the basic necessary level. Front-facing cameras, on the other hand, have traditionally been afterthought additions — making them better is a relatively simple act of retreading the resolution and clarity evolution that’s taken place at the back of your smartphone.
