Macworld asked me to write about how the iPhone 6s compares to the iPhone 6 considered solely as cameras. In other words, how much better is the 6s’s camera than the 6’s?

It was a hugely fun thing to write. Well, it was logistically a complete pain in the arse as it had to be turned around quickly, and on a weekend when I thought I’d be able to give my wife a break from wrangling our sometimes fractious baby daughter I was instead haring all over town taking photos then locking myself away for snatches of time in my office to try to analyse the shots and marshal my thoughts into a coherent narrative.

But when I eventually turned in at 2am early on Sunday morning, having completed a first draft, I was buzzing. It’s a really simple thing, but it was so lovely to have the opportunity – thanks, Susie! – to set out with an open mind, take a bunch of carefully-planned sample shots and footage, and then sit down, sort through it all dispassionately, and have the rewarding experience of seeing original conclusions and judgements emerge which I’m confident in and which I think are genuinely useful.

It’s quite long – and boy, do I fret about writing flabby prose; I hope my editor friends won’t be secretly thinking I could easily have cut it in half – but there’s a tl;dr version at the end if you want to skip straight to that. Set aside 10–20 minutes and have a read; I’m proud of this one.
