The early cameras were very boxy things with the very first often being similar in size to a coffin. the first camera was called a camera obscura. it was invented in the middle ages to aid artists in doing realistic paintings.
Photographic cameras were a development of the camera obscura, a device possibly dating back to the ancient Chinese and ancient Greeks, which uses a pinhole or lens to project an image of the scene outside upside-down onto a viewing surface. An Arab physicist, Ibn al-Haytham, published his Book of Optics in 1021 AD.He created the first pinhole camera after observing how light traveled through a window shutter. Ibn al-Haytham realized that smaller holes would create sharper images. Ibn al-Haytham is also credited with inventing the first camera obscura.he history of the camera can be traced much further back than the introduction of photography. Cameras evolved from the camera obscura, and continued to change through many generations of photographic technology, including daguerreotypes, calotypes, dry plates, film, and digital cameras.
