The Guardian launched the Eyewitness photography app over two years ago to showcase some of the world’s most distinctive and provocative photographs per day.

Now users will be offered dozens of extra images each month through a new ‘Eyewitness Premium’ in-app subscription service, which costs £1.49 a month.

The premium version will provides subscribers with Eyewitness Extra, which comprises three additional pictures per day selected especially for the app by the Guardian’s picture desk as well as access to the new ‘Eyewitness Series’ collections that comprises a single standout picture each day during major world events.

The app will come pre-loaded with an Olympics collection and a new collection will begin later this month with the London 2012 Paralympics.

For those not wanting to pay, which with such a good website is the Guardian reader way, they will still be able to view, favourite and share the original Eyewitness image of the day free of charge.

A nice touch to the app is that each image is accompanied by a “pro tip”, to give professional insights into the composition or technical specification of a particular image. A real bonus considering the surge in digital photography.

Roger Tooth, the Guardian’s Head of Photography, said: “We’ve been blown away by the global appeal of the Eyewitness app since its inception in 2010, and it’s been wonderful to see hundreds of thousands of people around the world engage with the photography we have chosen to feature on the app.

“Today’s new features mean that – while users will still be able to enjoy one image per day for free as they always have done – photography fans will now be able to enjoy more great news images from around the world every day.”
