Photography as a medium is less than 200 years old. But in that brief span of history, it has evolved from a crude process using caustic chemicals and cumbersome cameras to a simple yet sophisticated means of creating and sharing images instantly.
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. He developed the camera obscura and took the first photo with it. It wasn’t ideal, though, because it took 8 hours of light exposure to make a picture, and the picture faded with time. Louis Daguerre invented a new way to take pictures.
Camera Obscura
Daguerrotypes and Calotypes
Louis Daguerre continued to experiment and by 1837 had created the first practical photographic process, which he named the daguerreotype . Daguerre treated a silver-plated sheet of copper with iodine vapor to give it a coating of light-sensitive silver iodide. After exposure in the camera, the image was developed by mercury vapor and fixed with a strong solution of ordinary salt (sodium chloride). Henry Fox Talbot perfected a different process, the calotype. As commercialized, both processes used very simple cameras consisting of two nested boxes. The rear box had a removable ground glass screen and could slide in and out to adjust the focus. After focusing, the ground glass was replaced with a light-tight holder containing the sensitized plate or paper and the lens was capped. Then the photographer opened the front cover of the holder, uncapped the lens, and counted off as many minutes as the lighting conditions seemed to require before replacing the cap and closing the holder.
Film Type Cameras
The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloidin 1888-1889. His first camera, which he called the “Kodak,” was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came pre-loaded with enough film for 100 exposures and needed to be sent back to the factory for processing and reloading when the roll was finished. By the end of the 19th century Eastman had expanded his lineup to several models including both box and folding cameras.
In 1900, Eastman took mass-market photography one step further with the Brownie, a simple and very inexpensive box camera that introduced the concept of the snapshot. The Brownie was extremely popular and various models remained on sale until the 1960s.
35mm
A number of manufacturers started to use 35mm film for still photography between 1905 and 1913. The first 35mm cameras available to the public, and reaching significant numbers in sales were the Tourist Multiple, in 1913, and the Simplex, in 1914.
Due to research and development at Leitz, using 35 mm cine film for still cameras while attempting to build a compact camera capable of making high-quality enlargements. it built its prototype 35 mm camera (Ur-Leica) around 1913, though further development was delayed for several years by World War I. It wasn’t until after World War I that Leica commercialized their first 35mm Cameras. Leitz test-marketed the design between 1923 and 1924, receiving enough positive feedback that the camera was put into production as the Leica I (for Leitz camera) in 1925. The Leica’s immediate popularity spawned a number of competitors, most notably the Contax (introduced in 1932), and cemented the position of 35 mm as the format of choice for high-end compact cameras.
TLR and SLR
he first practical reflex camera was the Franke & Heidecke Rolleiflex medium format TLR of 1928. Though both single- and twin-lens reflex cameras had been available for decades, they were too bulky to achieve much popularity. The Rolleiflex, however, was sufficiently compact to achieve widespread popularity and the medium-format TLR design became popular for both high- and low-end cameras.
A similar revolution in SLR design began in 1933 with the introduction of the Ihagee Exakta, a compact SLR which used 127 rollfilm. This was followed three years later by the first Western SLR to use 135 film, the Kine Exakta (World’s first true 35mm SLR was Soviet “Sport” camera, marketed several months before Kine Exakta, though “Sport” used its own film cartridge). The 35mm SLR design gained immediate popularity and there was an explosion of new models and innovative features after World War II. There were also a few 35mm TLRs, the best-known of which was the Contaflex of 1935, Several other camera makers also entered the SLR market in the 1950s, including Canon, Yashica, and Nikon.
Instant Cameras
While conventional cameras were becoming more refined and sophisticated, an entirely new type of camera appeared on the market in 1948. This was the Polaroid Model 95, the world’s first viable instant-picture camera. Known as a Land Camera after its inventor, Edwin Land, the Model 95 used a patented chemical process to produce finished positive prints from the exposed negatives in under a minute.
The Polaroid lineup had expanded to dozens of models by the 1960s. The first Polaroid camera aimed at the popular market, the Model 20 Swinger of 1965, was a huge success and remains one of the top-selling cameras of all time.
Digital Cameras
Digital cameras differ from their analog predecessors primarily in that they do not use film, but capture and save photographs on digital memory cards or internal storage instead. Their low operating costs have relegated chemical cameras to niche markets. Digital cameras now include wireless communication capabilities (for example Wi-Fi or Bluetooth) to transfer, print or share photos, and are commonly found on mobile phones.
By the late 1980s, the technology required to produce truly commercial digital cameras existed. The first true portable digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 2 MB SRAM memory card that used a battery to keep the data in memory. Digital camera sales continued to flourish, driven by technology advances. The digital market segmented into different categories, Compact Digital Still Cameras, Bridge Cameras, Mirrorless Compacts and Digital SLRs. One of the major technology advances was the development of CMOS sensors, which helped drive sensor costs low enough to enable the widespread adoption of camera phones.
