Guardian News and Media has proposed changes to the terms and conditions under which it commissions photography. If you are a photographer who could be affected by the proposals, please sign the letter below. - - - - - - - - - - To: Chris Elliot, Managing Editor, Guardian News and Media We have been made aware of your changes to terms and conditions for commissioned photography, issued to contributors on 28 July 2009. At a time when press photographers are suffering severe hardship as a result of the economic downturn, it comes as a further blow to be informed that GNM demands unlimited re-use of our photographs free of charge. The reduced demand for photographs during the recession will force many photographers out of business. If we have to allow free use of our images this procession will be accelerated. The Guardian and Observer have a proud record of championing the cause of downtrodden workers in other countries. We call upon GNM and the Scott Trust to behave in a manner consistent with their editorial policy, and respect the rights of their suppliers to be treated in a fair and equitable manner and in accordance with the spirit of the Copyright, Designs and Patents Act 1988. As a first step, we urge you to enter into meaningful negotiations with the National Union of Journalists and other organisations representing photographers. - - - - - - - - - - Please note: The petition website may request a donation at the end of the process but there is no need to pay.
