Did you know that the first lead to modern day photography and cameras started around 1000AD by Alhazen? The “Pinhole camera” or “Camera Obscura” reflected images upside down and was typically used for viewing and drawing.
From this, Joseph Nicephore Niepce created the first photographs calling them “heliographs” or sun prints which were the prototype for modern photographs.
Louise Daguerre then developed the first practical process of photography by partnering with Niepce to expand upon his process and findings. The more effective method that Daguerre eventually discovered in 1839 he named after himself, the daguerrotype.
In 1841, Henry Fox Talbot invented the first negative by sensitizing paper to light with a silver salt solution. Once this process was perfect, Talbot named it “Calotype” meaning beautiful picture is Greek.
Wet Plate Negatives also contributed greatly to the advancement of photography because once sensitized materials could be coated on plate glass, the image was more stable and detailed than ever before.
George Eastman, in 1889, developed the flexible film roll which was unbreakable and could be rolled which made the mass-produced camera a reality and lead to the Box Camera, more famously, the Kodak camera. A year later the delicate paper film was changed to a plastic base ultimately leading to Canon’s development of the first digital electronic still camera in 1984.
