IMAGE QUALITY & PERFORMANCE - APPLE IPHONE 6S PLUS
The Apple iPhone 6s Plus’ colors are quite pleasing in good light, however, its white balance tends to veer warmer, with some images looking more yellow than usual. The lens is mostly sharp, with the right upper and lower corners slightly soft. There is no barrel distortion. When viewed up close, the images lack fine detail, especially when compared against the Samsung Galaxy Note5.
The iPhone 6s Plus does manage to preserve whatever details it captures while shooting in low light. That would be a given since its images are shot at low ISOs, even in dark situations. To get such low ISO settings, the iPhone 6s Plus has an alarming habit of shooting at dangerously low shutter speeds. And yet, the images are still stable and sharp, which I chalk up to its excellent optical image stabilization. Even at the higher setting of ISO 640, the iPhone 6s Plus strikes a good balance between noise reduction and detail retention.
HDR images tend to be underexposed, but the iPhone 6s Plus consistently gets the best panoramas out of all five smartphones.
The iPhone 6s Plus’ 4K videos are fine in good light, has some noise in low light, and has hardly any rolling shutter. Its optical image stabilization is surprisingly good, the difference is obvious when you compare it against the non-stabilized shot taken by the Nexus 6P. This makes it the best 4K video camera, out of all the five flagships.
