This document provides a timeline and overview of important developments in photographic technology from 1841 to 2000. It describes early processes like the Calotype and wet plate collodion which improved exposure times. It then covers the introduction of color photography, film rolls, simplified cameras, camcorders, digital cameras, and camera phones - tracing the evolution of photography from complex chemical processes to ubiquitous digital cameras. Key inventors and their innovations are noted, showing the progressive simplification and wider availability of camera technology over time.
