Graham Flint is the sort of man who uses the structural bracing of a nuclear reactor's safety door as a camera stand. The bracing secures his camera casing to the inside of his minivan and is indicative of the precision and focus with which he approaches all aspects of his life, none more so than his current and most ambitious project: a 1,000-shot survey of America at the dawn of the 21st century, his Portrait of America, taken with the camera he designed and built, the highest-resolution landscape camera ever created.
