A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek (phos) "light" and (graphe) "representation by means of lines" or "drawing", together meaning "drawing with light".
Here are some of the earliest photographs ever taken and their historical significance.
Boulevard du Temple, Paris, IIIe arrondissement, Daguerreotype. The purportedly first picture of a living person. The image shows a busy street, but due to exposure time of more than ten minutes, the traffic was moving too much to appear. The exception is the man at the bottom left, who stood still getting his boots polished long enough to show. Note that the image is a mirror image.
Tartan Ribbon, photograph taken by James Clerk Maxwell in 1861. Considered the first colour photograph. Maxwell had the photographer Thomas Sutton photograph a tartan ribbon three times, each time with a different colour filter over the lens. The three images were developed and then projected onto a screen with three different projectors, each equipped with the same colour filter used to take its image. When brought into focus, the three images formed a full colour image.
In 1887, using a series of trip wires, Eadweard Muybridge created the first high speed photo series which can be run together to give the effect of motion pictures. It helped solve the myth of whether horses ever have all four legs off the ground at the same time.

The oldest heliographic engraving known in the world. It is a reproduction of a 17th century Flemish engraving, showing a man leading a horse. It was made by the French inventor Nicéphore Niépce in 1825, with an heliography technical process. The Bibliothèque nationale de France bought it 450,000 € in 2002, deeming it as a 'national treasure'.
View from the Window at Le Gras, the first successful permanent photograph created by Nicéphore Niépce in 1826, Saint-Loup-de-Varennes. Captured on 20 × 25 cm oil-treated bitumen. Due to the 8-hour exposure, the buildings are illuminated by the sun from both right and left.
