“Imagine, he suggests, a photojournalist covering a presidential speech whose audience includes a clutch of protesters. Using a traditional camera, he says, ‘I could easily set my controls so that what’s in focus is just the president, with the background blurred. Or I could do the opposite, and focus on the protesters.’ A Lytro capture, by contrast, will include both focal points, and many others. Distribute that image, he continues, and ‘the viewer can choose—I don’t want to sound professorial—but can choose the truth.’” - “The Revolution in Photography,” The Atlantic Monthly, http://bit.ly/rKfXXO
