About Welcome to my site. Here you will find summaries of my work, videos to watch, papers to download, images to study and links to pursue. I have three areas of interest - photography, multimedia and politics. I am particularly concerned with (1) how documentary photography, photojournalism and satellite imaging visually enact our world; (2) how multimedia technologies are transforming the capacity of photography to tell stories about our hybrid world; and (3) how issues of identity and representation help structure international politics. A full CV/resume is available here. As professor of cultural and political geography at Durham University in the UK, I am associated with the Durham Centre for Advanced Photography Studies. In 2009 I have a fellowship at Durham's Institute for Advanced Study to work on photographs from the Sudan archive for my 'Geopolitics and Visuality' project.

Photographic retouching exposed April 29th, 2009 The issues surrounding photographic meaning, manipulation and Photoshop have been prominent recently (see my previous posts here and here, with some updates amongst the comments for each). Via Fred Ritchin's After Photography (see his 24 April post) comes news of a Swedish government project Girlpower dealing with sexism in advertising. One element is a magazine cover where, step-by-step, you can un-do the manipulation of the model to see how the glamorous cover was produced. You can go through each of the twelve changes that have been made, and at the end click on a red button to see the complete before and after images. We know it happens, but in this case, seeing is really believing.

Photographic truth and Photoshop April 17th, 2009 Photography's anxiety about truth, manipulation and reality has been on show recently. In different ways and from different contexts, people have been asking: "how much Photoshop is too much"? From the realm of fashion, French Elle is being celebrated for running a cover story in which the models photographs have not been 'Photoshopped' (thereby confirming, as I've noted previously, that digital manipulation is the norm in this visual domain). From the world of photojournalism, blogs like 1854, PDNPulse and the Online Photographer (with a follow-up here) have been buzzing with the story of the Danish photographer Klavs Bo Christensen who was excluded from that country's Picture of the Year competition for excessive colour manipulation of his Haiti story. Along with two others, Christensen was asked to submit his RAW files to the competition judges who felt that the colour in his photographs had been excessively saturated (their debate can be heard here), and removed his images from the competition as a result. Christensen was subsequently happy to have his files put on the web for comparison and discussion, thereby performing an important service to the photographic community.

Photographic truth and manipulation February 23rd, 2009 We know photographs can be false yet we want them to be true. Indeed, the desire for photographic veracity has persisted, perhaps even intensified, even as knowledge about image manipulation becomes more widespread. Reflecting on the Oscar ceremonies, MediaGuardian has documented the widespread use of Photoshop to enhance celebrity photographs in fashion and gossip magazines. Every cover, says one media insider, has been altered to some degree, with some of these changes exposed in the "Photoshop Hall of Shame" and "Photoshop Disasters". So common is the practice that when an October 2008 Newsweek cover of Vice Presidential candidate Sarah Palin was not airbrushed, conservative anchors on Fox television complained that this amounted to liberal bias. (Fox knew about the political power of such changes because it had earlier manipulated the photos of two New York Times journalists it wanted to discredit).
