Tate Britain has this afternoon issued a statement after a backlash over the terms of use of press photographs documenting the Turner Prize exhibition.

NEWS UPDATE 5 OCTOBER

Earlier today it was reported that organisers of the Turner Prize exhibition had effectively banned press photographs from being used to show the gallery in a negative light, under the terms of a new contract.

The Evening Standard and the Press Association were among the news outlets threatening to boycott the launch of the exhibition at Tate Britain today.

In an official statement issued late this afternoon a Tate Britain spokeswoman said: ?Tate [galleries] have a standard filming and photography indemnity form which we have been using for at least ten years.

?Such forms are widely used by arts organisations. Journalists are not required to sign this form, only film crews and photographers.

?Following discussions with picture desks, we are currently reviewing some of the terms of the form.?

Photographers had protested over a contract that reportedly asked photographers to grant the gallery permission to copy, reproduce, record, store and disseminate their photos, without paying royalties.

Times photographer Richard Pohle had told journalists: ?We are not prepared to sign a contract that leaves us open to being sued by the Tate if our pictures are used next to an article that criticises the gallery.?
