The history of the camera can be traced much further back than the introduction of photography. Photographic 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.
Photographic cameras were a development of the camera obscura, a device 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. 
The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light.

From here, photography has come a long way. Now, there are digital cameras that can have different lenses, perfectly clear and crisp images and super fast capture. They can be instantly printed and can be stored digital forever. By 2010, almost all mobile phones featured built-in high resolution digital video cameras and many cameras featured built-in GPS, allowing for automatic real-time geotagging.

The Canon EOS (Electro-Optical System) autofocus 35 mm film and digital SLR camera system was introduced in 1987 with the Canon EOS 650 and is still in production as Canon's current DSLR and recently released Canon EOS Mirrorless interchangeable-lens camera (MILC) systems. As of 2007, Canon has released no fewer than 40 EOS SLR camera models, starting with the introduction of the EOS 650 in 1987. Through the tracking of eyeball movements, EOS cameras equipped with eye-controlled focusing (ECF) are able to choose the appropriate autofocus point based on where the user is looking in the viewfinder frame. ECF comes especially useful in sports photography where the subject may shift its position in the frame rapidly.
