From 1664 to 1666, Photography as we know it did not exist, as it was not invented until the early 19th century. However, this period saw significant advancements in optics and chemistry that would later contribute to the development of photography. Notably, the invention of the camera obscura, which had been used for centuries, was refined during this time, laying foundational concepts for capturing images. Additionally, experiments with light-sensitive materials began to emerge, paving the way for future photographic techniques.
