A few days ago a number of newspapers reported that, following similar moves by a number of other UK institutions, the National Gallery in London has changed its strict no-photos-(please) policy, “after staff realised they were fighting a losing battle against mobile phones”, The Telegraph explains.

In particular, this decision has been motivated by the difficulties that have arisen to distinguish between visitors using the free wi-fi provided by the Gallery “to research paintings” and “those trying to take pictures with mobile phones.”
