Dynamic range has always been the Achilles’ heel of smartphone photography. It is the one aspect where dSLRs shine and simply cannot be outdone by our phones. (There also used to be auto-focusing on this list, but with phase detection AF on iPhone 6 Plus, Apple has raised the bar really high.)
Among several additions to iOS 8 comes burst mode capability — click and hold for several shots in quick succession. My iPhone 6 Plus shoots 10 frames per second which is almost twice the speed of my Nikon D600, which shoots 5.5 frames per second. Of course, the fact that the sensor is bigger, more memory needs to be written and other such factors come into play here.
The biggest advantage of this burst mode feature means making HDR (High Dynamic Range) photos with iPhones is no longer a software-only affair spewing out fake HDR/grunge images, but actual multiple bracketed exposures combined into one HDR photo.
