I’m no photographer. I’m a visual anthropologist (yes there is such thing). And as such, I want to say to photographers and image producers: either you come up with narratives that respect the subject (hint= do not deny agency over the discourse about themselves, do no deny dignity) + tells something interesting (hint= interrogates the interrelations that make up the complexities you should be interested in) , or you don’t shoot. It’s that simple.
Now let us examine some of her fine visual anthropological study, available here: remembering hell
A quick google around reveals that these are literally the standard tourist snaps of the standard objects everyone takes when they go to Choeung Ek and take the standard 1 hour (or whatever it is) Killing Fields tour. Keep in mind that, for all we know, some of the skulls she so dutifully photographs could be muslim skulls, or skulls belonging to some other religious group, the original owners of those skulls might not be thrilled with the current regime using their body parts for display. Maria Lopez doesn't care, though.
Not a hell of a lot of that "respecting the subject" here (she "can't" speak to the survivors, everyone else "doesn't" speak to them, everyone else "wants a piece of them" and Maria bravely photographs them, or some goddamned thing). Not a hell of a lot of interrogating the interrelationships here. She gives no evidence that she has even read the wikipedia page on the Cambodian Genocide. There are "interrelationships" which could be "interrogated" here, but she doesn't bother, doesn't care, she's had her 1 hour tour and she's done.
By being a standard tourist, she is simply regurgitating the narrative the current Cambodian government wants to promote which is at the very least a bit problematic (those damned skulls).
Tourist girl goes to Cambodia, takes the standard tour, takes the standard snaps, writes a few hundred words of weepy bullshit about events that happened decades before she was born and half a world away, and throws it up on the web as "visual anthropology", then takes to twitter to decry unethical photojournalism.
This is the quality of person we have "policing" the ethics of an industry. This is the quality of person that presumes to dictate to Magnum how they ought to conduct themselves. She makes James Curtis look like an intellectual superhero.
