Earlier this month, James McAvoy stopped a performance of Macbeth at Trafalgar Studios to ask a member of the audience to stop filming it. A bold move that risked ruining the show for those who chose not to view the live event through a 2D screen. And, arguably, any actor less sure of his status as one of Britain’s best wouldn’t dare be so impertinent. But, in principle, McAvoy has a point.

The Yeah Yeah Yeahs cottoned on to the annoyance of phone-viewing and posted a pre-emptive notice to their fans banning the use of phone cameras and filming. The Guardian’s Michael Hann has argued that cameraphone footage is infuriating and pointless. Using mobiles and tablets to document a live event is not only annoying to those around them – judging from the comments on Hann’s article, many agree with this point – it’s also detrimental to the production itself.

When you see an iPhone or iPad set to camera-mode during an event, it’s rarely so the owner can enjoy the show over and over again at home: it’s for sharing on social networks. And for artistic productions, this kind of exposure is damaging. Posting self-shot videos and photos of gigs, productions, performances and art exhibitions undermines the integrity of the original. Production teams work hard to create an image for their show, often selecting specific moments during the production to be shown to the press, while reserving others as surprises. Inevitably, if someone documents what they deem to be the best moments of a production and strew them over Twitter, you would be less inclined to bother spending money on going to see the show live.

Take No Fit State Circus, currently performing at the Roundhouse, as an example. Type their name into Twitter or YouTube (followed by the word “live”) and a barrage of pictures and videos taken on smart devices will flood your newsfeed. These aren’t produced by the company, they’re snapshots posted by viewers wanting to share their experience of the show with friends and followers – a fragmented portrayal of the production.

Arguably, footage posted on social media could be deemed as publicity, providing the show with free exposure. Social networks are now well-known for their ability to generate ‘hype’ about a certain product or event. But there’s a reason why institutions like The Southbank Centre have a no filming policy: the joy of seeing a play or visiting an art installation is in the physical live experience.

Your peripheral vision soaks up your surroundings. The sound design creates a three-dimensional scene and you feed off the atmosphere in the space, reacting in real-time to other viewers or participants. None of this can be sufficiantly captured on film. Instead, you’re presented with a cut and paste job, left to make your mind up about whether or not to visit a production based on someone else’s selected clips. Plus, they may well have exposed you to the most climactic point of the piece – this has happened to me – which thoroughly ruins any appetite you once had of going to see it.

I’m not averse to technology fusing with the arts when it is complimentary, as this advert for a new robot demonstrates. We may not be far away from a time where remote viewing becomes the norm and viewers can “visit” exhibitions using robots with iPad conectivity. It may not be the same as physically attending a gallery, but as least you will create an interpretation of the art based on your own experience of it.

However, until the majority of performances and installations are created with smartphone technology in mind, pictures and videos published on social media networks are merely dumbed-down replicas of the original cultural product. Unrepresentative and misleading, they devalue the original production. I would love to see technology further incorporation into the arts, but otherwise, smart-phone filming has no place in artistic performances. In my internet utopia, our cultural spaces would be camera-free, allowing the genius behind every piece of art to remain a mystery.
