Apple's latest iPhones can shoot brighter, more detailed and wider colour gamut photos. Instagram has responded in kind by enabling wide colour capture support which brings all that detail, depth and colour on Instagram snap.
Even better, Live Photos now import seamlessly and automagically into Instagram in the form of Boomerang videos which have recently gained renewed popularity for some reason. Best of all these new iPhone 7 features have been trickling out automatically so users don't need to do anything, if you have supported iPhones, they are most likely running the latest features already.
