Tinie Tempah has criticised Apple's idea for new technology that would stop music fans filming live gigs.

The rapper said: "Just move with the times, stop trying to block people from doings things. It all works."

The 22-year-old told Newsbeat he doesn't mind fans filming at his gigs, calling it "the biggest form of promo".

Earlier this month, Apple applied to patent a system that could switch off a smartphone's camera if it senses the user is trying to record a live event.

Tinie, real name Patrick Okogwu, is just one of a number of artists who have spoken out about the US firm's innovation.

There's like thousands of them sometimes at once filming one song, its like they're not there in the moment Alex Trimble Lead singer of Two Door Cinema Club

Kaiser Chiefs frontman Ricky Wilson has said although he doesn't mind fans filming the band's gigs, he'd rather they spent time "enjoying" them instead.

"It's not really enjoying the moment is it? Personally I wouldn't even take a phone to a gig, because I'd want to throw myself around too much.

"You can't really crowd surf with an iPad."

Fans' experience

Guitar band Two Door Cinema Club recently asked fans on their website for footage of their experience at a gig at London's O2 Brixton Academy in June.

Lead guitarist Sam Halliday said they enjoyed seeing their performances through fans' eyes, but thought there was a time and a place for cameras at gigs.

"Sometimes if we play a new song or something a lot of people would film and they're more concentrating on filming rather than enjoying the music," he said.

"Sometimes that does get a little bit annoying."

Lead singer Alex Trimble said: "There's like thousands of them sometimes at once filming one song, its like they're not there in the moment.

"They're experiencing it through a lens. I would prefer it if fans just enjoyed it rather than taking the time to film it themselves."

Apple applied to the US Patent and Trademark Office on 2 June asking for ownership of the new technology.

The system would involve a device's camera being disabled if it picks up infrared light "in areas where picture or video capture is prohibited".

It's not clear when the firm might try to develop the concept, telling Newsbeat they don't comment on patent applications.
