Waitress Valerie J. Cochran started her photoblog partly as a reaction to customers who view restaurant workers as robots and not real people. Based in Berkeley, California, her photos are often of ordinary people and places. Lecturer David J. Nightingale is another photoblogger -- one of the thousands of people around the world using the net to publish photographs that offer a glimpse into life. His website has a different photo every day, attracting 4,000 unique visitors daily, and was chosen by Time magazine as one of the Top 50 coolest websites of 2005. Each photo captures a different aspect of his life -– from family portraits to studies of his environment and wider world. This BBC series showcases some of the inspiring work of these exceptional photobloggers.
