There was a blink and you miss it moment during the keynote that I feel isn’t getting enough play. Eddie Cue, when discussing the new AppleTV 4K, casually mentioned that not only will 4K movies from major studios not cost more than HD movies (25$ in Canada), but also that movies you have already bought will be upgraded for free. This is probably the best news of the entire keynote if you’re like me and have a massive library of iTunes movies (and TV).
Apple has posted a whole series of videos to show you how to get the most out of your iPhone camera. If you’re a photographer you may not need these, but the videos are also just solid tutorials on the iPhone camera controls. It also explicitly calls out iPhone 7 but the majority of the info works for any iPhone.
Plus, it’s just a well designed page full of videos.
