Beginning of Photography
Photography has come a long way in considerably short period of time. In about 200 years, the camera developed from a plain box with a pinhole, that produced blurry images to the high resolution produced in our DSLRs and smartphones today.
The story of photography is fascinating and books are written that still only cover portions of its amazing historical route taken thus far. That being so, I want to just take a relatively brief look at the highlights and major developments of this impressive scientific form of art.
The First Cameras
Though I stated 200 years; the basic concept of photography has been with mankind since the 5th-century. An Iraqi scientist developed something called the camera obscura in the 11th-century and that is when the art of photography came alive.
Still the camera did not actually record images, it simply projected them onto another surface. However, it was truly the beginning of getting us to where we are today. The images were upside down so they would often be traced in order to obtain an accurate drawing of the subject, such as a building for instance.
The first camera obscura used a tent with a pinhole in order to project an image from outside of the tent into the darkened area. Now we fast-forward to the 17th-century – the camera obscura became small enough to be portable, relatively speaking (the portable version is in the drawing the the right of this paragraph. Basic lenses to focus the light were now being introduced as well.
The First Permanent Images
Photography as we know it today didn’t begin until the late 1830s. This came about in France when Joseph Nicéphore Niépce used a portable camera obscura to expose a pewter plate coated with bitumen to light. When he did this, the first recorded images that did not quickly fade away was produced.
Niépce’s success led to a number of other experiments, which were successful. After these new discoveries photography progressed quite rapidly. Emulsion plates and wet plates were developed almost simultaneously in the mid- to late-1800s.
Within each type of emulsion, photographers experimented with different chemicals and techniques.
The following are the three that were instrumental in the development of modern photography.
Niépce’s experiment led to a collaboration with Louis Daguerre. The result was the creation of the daguerreotype, a forerunner of modern film. An image of the Daguerreotype Camera is included in this paragraph.
A copper plate was coated with silver and exposed to iodine vapor before it was exposed to light.
To create the image on the plate, the earlier daguerreotypes had to be exposed to light for up to 15 minutes. The daguerreotype was very popular until it was replaced in the late 1850s by emulsion plates.
Emulsion Plates. Emulsion plates, or wet plates, were less expensive than daguerreotypes and took only two or three seconds of exposure time. This made them suited to portrait photography, which was the most common photography at the time. Many photographs from the Civil War were produced on wet plates.
These wet plates used an emulsion process called the Collodion process, rather than a simple coating on the image plate. It was during this time that bellows were added to cameras to help with focusing.
Two common types of emulsion plates were the ambrotype and the tintype. Ambrotypes used a glass plate instead of the copper plate of the daguerreotypes.
Tintypes used a tin plate. While these plates were much more sensitive to light, they had to be developed quickly. Photographers needed to have chemistry on hand and many traveled in wagons that doubled as a darkroom.
Dry Plates. In the 1870s, photography took another huge leap forward. Richard Maddox improved on a previous invention to make dry gelatine plates that were nearly equal with wet plates in speed and quality.
These dry plates could be stored rather than made as needed. This allowed photographers much more freedom in taking photographs. Cameras were also able to be smaller and could be hand-held. As exposure times decreased, the first camera with a mechanical shutter was developed.
Cameras for Everyone
Photography was only for professionals and the very rich until George Eastman started a company called Kodak in the 1880s.
Eastman created a flexible roll film that did not require the constant changing of solid plates. This allowed him to develop a self-contained box camera that held 100 film exposures. The camera had a small single lens with no focusing adjustment.
The consumer would take pictures and send the camera back to the factory for the film to be developed and prints made, much like modern disposable cameras. This was the first camera inexpensive enough for the average person to afford.
The film was still large in comparison to today’s 35mm film. It took until the late 1940s for 35mm film to become cheap enough for most people to afford.
The Horrors of War
Around 1930, Henri-Cartier Bresson and other photographers began to use small 35mm cameras to capture images of life as it occurred rather than staged portrait. When World War II started in 1939, many photojournalists adopted this style.
The posed portraits of World War I soldiers gave way to graphic images of war and its aftermath. Images such as Joel Rosenthal’s photograph, Raising the Flag on Iwo Jima brought the reality of war across the ocean and helped galvanize the American people like never before. This style of capturing decisive moments shaped the face of photography forever.
The Wonder of Instant Images
At the same time that 35mm cameras were becoming popular, Polaroid introduced the Model 95. Model 95 used a secret chemical process to develop film inside the camera in less than a minute.
This new camera was fairly expensive but the novelty of instant images caught the public’s attention. By the mid-1960s, Polaroid had many models on the market and the price had dropped so that even more people could afford it.
In 2008, Polaroid stopped making their famous instant film and took their secrets with them. Many groups such as The Impossible Project and Lomography have tried to revive instant film with limited success.
Even with filters (hardware and software such as instagram), it has been suggested that as of 2016, it is difficult to replicate the quality that a Polaroid produced.
Advanced Image Control
While the French introduced the permanent image, the Japanese brought easy control of images to the photographer.
In the 1950s, Asahi, founded in 1919, (which later became Pentax, and now merged with Ricoh as of 2015) introduced the Asahiflex and Nikon introduced its Nikon F camera. These were both SLR-type cameras and the Nikon F allowed for interchangeable lenses and other accessories.
For the next 30 years, SLR-style cameras remained the camera of choice and many improvements were introduced to both the cameras and the film itself.
Introducing Smart Cameras
In the late 1970s and early 1980s, compact cameras that were capable of making image control decisions on their own were introduced. These “point and shoot” cameras calculated shutter speed, aperture, and focus, leaving photographers free to concentrate on composition.
These cameras became immensely popular with casual photographers. Professionals and serious amateurs continued to prefer to make their own adjustments and enjoyed the image control of SLR cameras.
The Digital Age
In the 1980s and 1990s, numerous manufacturers worked on cameras that stored images electronically. The first of these were point-and-shoot cameras that used digital media instead of film.
By 1991, Kodak had produced the first digital camera that was advanced enough to be used successfully by professionals. Other manufacturers quickly followed and today Canon, Nikon, Pentax, and other manufacturers offer advanced digital SLR (DSLR) cameras.
Even the most basic point-and-shoot camera now takes higher quality images than Niépce’s pewter plate, and smartphones can even pull off a high-quality printed photograph.
