100 Ideas That Changed Photography by Mary Warner Marien: This book chronicles the most influential ideas that have shaped photography from the invention of the daguerreotype in the early 19th century up to the digital revolution and beyond.
It’s an interesting resource to dip into from time to time. It is arranged in a broadly chronological order to show the development of photography and the ideas that contributed to photography as its stands today. The book includes innovative concepts, cultural and social incidents, technologies, and movements. Each idea is presented well through text and good visuals, and explores when the idea first evolved and its subsequent impact on photography today. A good reference to be used again and again.
