The book "Lexington and Concord: A Chamber Impression" was written by Samuel Chamberlain himself. In this book, the author travels back in time, talking about the events that took place in Lexington and Concord, first abstracting from the usual historical texts, and working on photographs of events and details of the time. Through the lens of the camera, the author tries to convey to the reader the atmosphere and reality of those events. The book "Lexington and Concord: Camera Impression" creates a unique opportunity to look at history through the prism of photographs and impressions from them.
