Using a new camera and lytro.com, The Missourian breaks new visual ground. “It was all theory and toys for us until the Illum,” Bentley said. The Illum, introduced just months ago, comes closer to the single lens reflex cameras that professionals use. It has a zoom telephoto lens and a digital focusing system. Instead of the massive arrays of up to 100 lenses used in early past light field cameras, the Illum uses a “megaray” sensor to create 40 versions of the photo. Its onboard processor converts that into a single “living” image.
