Eyewitness was originally launched in April 2010 with the financial backing of Canon UK. Now, after more than 920,000 downloads and an average of 11.5 million page views per month, The Guardian is updating the app to bring more visual content.

The new in-app service called Eyewitness Premium is available as a subscription for £1.49 a month.

In addition to the original Eyewitness image of the day, which anyone can view, share and archive for free, subscribers will receive access to three additional pictures each day and to the Eyewitness Series collection, which provide a single standout during major world events.

"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," says Roger Tooth, the Guardian's head of photography. "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."
