The images and stories captured in The Human Face of Big Data are the result of an extraordinary artistic, technical and logistical juggling act aimed at capturing the human face of the Big Data Revolution. Big Data is defined as the real time collection, analyses and visualisation of vast amounts of the information. This raw information is fuelling a revolution which many people believe may have as big an impact on humanity going forward as the Internet has over the past two decades. It enables us to sense, measure and understand aspects of our existence in ways never before possible. The Human Face of Big Data captures, in glorious photographs and moving essays, an extraordinary revolution sweeping, almost invisibly, through business, academia, government, healthcare and everyday life.
