In this episode we explore the foundations of photography that lead to the creation of George Eastman's Kodak Brownie. By exploring the progression through the camera obscura, Heliography, Calotypes and wet plates we see how the original desire to capture light eventually leads to dry plate negatives and the world of modern photography - a world that becomes the foundation for a culture obsessed with picture taking that will later be created by Kodak and its Brownie camera.
