You’d think that a modern photojournalist covering the world’s biggest sporting event for one of the UK’s biggest papers would use a serious camera for the job. Not The Guardian’s Dan Chung, who is using an iPhone 4S.

Perhaps we should clarify - Chung is using the iPhone 4S to live-blog the event from a photographer’s perspective. This means lots of small, incidental snaps taken and uploaded immediately. We can think of no better device to do that (well, apart from maybe a Nokia PureView 808).

Even then, he’s needed a little help to get his shots. That help comes in the shape of a clip-on Schneider lens (all the better to get a close-up of Michael Phelps making like a salmon) and the popular Snapseed app for tweaking and editing the images.
