The Photography timeline, up to present times

As the Camera Obscura becomes a reality, the possibility of fixing an image on metal or paper becomes a reality:
Photography is born!

1814	Joseph Nicéphore Niépce (1765-1833) achieves the first photographic image with Camera Obscura - however - the image required eight hours of light exposure and later faded.
1819	Sir John Herschel, an accomplished scientist and astronomer - in one of his experiments as a chemist - discovered the photographic fixer, based on the action of hyposulfite of soda on otherwise insoluble silver salts, which led to the use of "hypo" as a fixing agent in photography. It was Herschel who coined the use of the terms "photography", "positive", and "negative" to refer to photographic images.
1826	First photo of Joseph Nicéphore Niépce done with the Camera Obscura (adjusted from the 'negative plate' on the left) which survived because it was fixed.

1835	The English scientist Henry Fox Talbot (1800-77) experiments the salted paper and calotype processes, precursors of the photographic negative.

1837	Louis Daguerre's first daguerreotype, taken in his studio, the first image that was fixed and did not fade. It needed 'only' under thirty minutes of light exposure.
1844	Louis Daguerre's portrait taken by Jean-Baptiste Sabatier-Blot.

1838	Boulevard du Temple, Paris - Daguerreotype taken by Louis Daguerre (1787-1851): one year later he had improved greatly, needing only about ten minutes of exposure, and we can see two persons in the image, in the lower left: a shoeshiner and his customer.
1839	The French Photographer M.De St-Croix exposed a silver-coated copper plate for several minutes to record a downtown London image.

1839	A vintage Daguerre-Giroux camera, after having been restored in the Reial Acadèmia de Ciènces y Arts de Barcelona.

1849 1855

Edgar Allan Poe and an unknown kid on a rocking horse: the Daguerreotype becomes an everyday reality, as exposure times become shorter and shorter.

1893	The Photographic Studio. Since exposure times were quite long, it was important to hold as still as possible the head of the portrayed person. This image seems to be a satire made in those times, though.
1898 ca.	The British-made 'Victo folding field Half-Plate camera' produced by Houghton from ca. 1898. Half-Plate is the negative size, being something in between the 4x5" and a 5x7" photographic glass plate. A small format for the end of the 19th century, as final prints on paper were made on contact.

1888	"You press the button, ... and we do the rest". Slogan by Eastman Dry Plate and Film Co. presenting its first consumer-type photographic camera: it came already loaded with film for 100 pictures, and could be reloaded.

1914	First Leica Wetzlar camera is created by its inventor Oskar Barnack and becomes available to the public. Small, light and with good lenses, very portable.

1929	The 120 film rolls guarantee a strong portability, and Rolleiflex takes advantage of this with its light cameras with double lenses: one lens for framing and focusing, the other for the actual photography. Image is seen right/left reversed, as in the Box type Camera Obscura, but you get used to it.

1932

The idea of using the 35 mm film is to take advantage of the film that has not been used by the cinema industry, and always have it available. The rangefinder feature is added to the Leica II in 1932, and that year both rangefinder and viewfinder cameras became available with interchangeable lenses.

1948	The American scientist Edwin Land unveils the first commercial instant camera, based on the invention of direct positive photography patented in 1939 by the chemist Rott Andor, and in a few years the Polaroid Corporation produces several models of consumer-friendly instant cameras and film.

1957	The Hasselblad 1000F 6x6 medium format camera is replaced by the 500C. Thanks to the use of 120 film, the fast changing film magazines, excellent optics and a through-the-lens viewing, it becomes an immediate hit for all photographers, even with its high price.

1960's	For nearly 30 years, Nikon's F-series SLRs (Single Lens Reflex) cameras will be the most widely used small-format cameras among professional photographers, and were used in Space Programs by the NASA.
1972	SX-70, the most developed and appreciated Polaroid camera.

1981	Photography goes DIGITAL. The Digital Still Camera Sony Mavica is the first commercially available camera which would provide electronic digital images and store them on a 3 1/2 Floppy Disk, with a resolution of 570x490 pixels.
1996	Kodak DC 20, the first digital camera with a strong success in the market. Good price and on-line sales (!!!) helped its diffusion. Specifications: 493x373 pixels resolution, 8 pictures, 1 MB storage, and a weight of 110 g for full portability.
