Lennon, Peter (31 de julio de 2003). «Magnum force». The Guardian. Consultado el 29 de agosto de 2014. «The last philosophical crisis for Magnum was the acceptance of colour. "Traditionally we are black and white," [Thomas] Hoepker says. "It was never a policy not to accept colour photographers. But acceptance came rather late and reluctantly. I am absolutely in favour. I am a colour photographer. The market called for colour and of course we have a few great colour photographers. There is Alex Webb [American], Gruyaert [Belgian] and Martin Parr [British]."».
