If Instagram had been available when I was working in Nicaragua in 1978, I'm sure I would have wanted to use it as a way of reporting directly from the streets during the insurrection.

We know photographers make frames, but we deeply believe they can also create frameworks.

I'm deeply interested in the photograph as a record of an encounter and enjoy putting myself in a timeline of image-makers, alongside other travelers, such as anthropologists, colonists, missionaries, even tourists. I do that to emphasize subjectivity, rather than privilege any single perspective - I see myself as only one of many storytellers.

I think photography has a huge potential to expand a circle of knowledge. There's a reality that we are all the more linked globally and we have to know about each other. Photography gives us that opportunity.

What worries me is that we want to close down our relationship to the world at large. In other words, people's instincts are overwhelmed by the amount of images, or they can't distinguish anymore between Rwanda or Bosnia or Somalia.

For a long time I've lived with the inadequacy of that frame to tell everything I knew, and I think a lot about what is outside of the frame.

The camera is an excuse to be someplace you otherwise don't belong. It gives me both a point of connection and a point of separation.
