What is the history of the camera obscura?

The camera obscura is a natural optical phenomenon where light entering a small hole in a dark chamber projects an inverted image onto the opposite surface. Over centuries, it evolved from a lensless natural phenomenon and darkened room into a popular drawing aid equipped with lenses in the 16th century. Eventually, this technology served as the foundational basis for the photographic camera developed in the 19th century, and historic versions like the one in Edinburgh became popular attractions.
