The iPhone camera has been a consistently emphasized point by Apple, and for good reason. The quality of pictures it can take increases with each iteration, and for most people, smartphone cameras have become their primary way to take photos. Of course, not all of our pictures come out looking like those highlight shots Apple uses in its ad campaigns, but several videos and a website the company just posted may help close the gap.
Most of the videos in the "How to Shoot on iPhone 7" website are vertically oriented for viewing on your phone, perfect to learn about features it has that maybe you never quite figured out how to use. Portrait mode, shooting stills during or shooting a vertical panorama are fairly easy to do, if you can find the right setting. Some of them focus on things like composition, in case you need more basic photography advice.
So, is this enough information for you to become a festival-flogging "influencer"? Probably not, but no matter phone or app you use it could help your next picture look a little bit better.
