The Fascinating Evolution of Cameras: From Pinhole to Smartphone

Imagine a life without cameras. Almost unimaginable, right? It’s become such a necessity that it had to be fused with our phones so that we could carry it with us conveniently.

Importance of Cameras

But what if they never existed? So many memories would have been lost and never carried forward. And think about education; it would have been such an inconvenience. Just think about how quick and easy it is to illustrate and explain something only because you were able to take a photo of it. Otherwise, good luck with explaining what an armadillo looks like!

With all that being said, let’s take a moment to contemplate and be thankful for the magnificent invention that cameras are and tip our hats to show respect to all the brave men and women who have dedicated their lives to making them available and affordable.

History of Cameras

At Camera Zone, our mission is to provide the most reliable updates on photography and cinematography gear, including expert opinions based on their performance and value.

The first camera can be traced back to as far as the fifteenth century. Abu Ali al-Hasan ibn al-Haytham is considered to be the father of optics and is credited with inventing the first pinhole camera, called the camera obscura. This contraption was a light-proof box with a small hole on one side for light to enter and strike a reflective surface to project an inverted but colored image.

The camera obscura was originally used to observe solar events and in drawing architecture. Back then, the technology to capture and record photos did not exist, and it wasn’t until the late 1830s when Joseph Nicéphore Niépce used a portable camera obscura to expose a pewter plate coated with bitumen to light. This is the first recorded image that did not fade quickly.

Following Niépce’s success, a number of other experiments progressed rapidly, and the development of photography took off. Daguerreotypes, emulsion plates, and wet plates were developed almost simultaneously in the mid to late nineteenth century.

Niépce’s success led to a collaboration with Louis Daguerre, and the result was the daguerreotype, a forerunner of modern film. The daguerreotype used a copper plate coated with silver and exposed to iodine vapor before it was exposed to light to create the image. Early daguerreotypes had to be exposed to light for up to 15 minutes and were very popular until they were replaced in the late 1850s by emulsion plates.

Emulsion plates quickly gained popularity as they required only a few seconds of exposure time, which made them much more suited to taking portraits. Many photographs from the Civil War were produced on wet plates, and 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, while tintypes used a tin plate. While these plates were much more sensitive to light, they had to be developed quickly, which meant that photographers needed to have chemistry at hand, and they often traveled in caravans, which doubled as darkrooms.

Photography took a huge leap forward in the 1870s when Richard Maddox improved on a previous invention to make dried gelatin plates. These plates were equal to emulsion plates in terms of speed and quality, but the most significant advancement was that they could be stored and developed at a much later time if needed. Photographers now had much more freedom in taking photos and also allowed for smaller cameras to be invented that could be handheld.

As the exposure time decreased, the first camera with a mechanical shutter was developed. Needless to say, cameras were very expensive and were only available to the very rich. It wasn’t until the 1880s when George Eastman established the company Kodak that average people were able to afford cameras. By then, cameras had started to take shape and look more like the cameras we are used to seeing today.

But still, it wasn’t as easy to develop photographs. The cameras did not have any focusing adjustments and had the capacity to shoot only 100 photographs. Once the camera had reached its capacity, the entire camera had to be sent to the factory to develop the photos. In 1913, Oscar Barnack began to research the possibility of inventing a smaller camera, and the Leica camera began to be commercialized after World War I.

Over the years, cameras began to shrink in size and become more sophisticated. The films used then were still pretty large and costly, but by the 1940s, the 35-millimeter film had become popular and cheap enough for the average person to afford.

Around 1948, Polaroid introduced its Model 95, which had the capacity to take and develop photographs in less than one minute. Even though this camera was fairly expensive, the general populace, awed by the camera’s instant imaging, took to the camera instantly.

Around the 1950s, Asahi, which later became Pentax, introduced the Asahi Flex, and Nikon introduced its Nikon F camera. These were both SLR-type cameras, and the Nikon F allowed for interchangeable lenses and other accessories. SLR-style cameras remained the camera of choice for the next 30 years.

Many improvements were made to both the cameras and the film itself. Compact cameras that were capable of making image control decisions on their own were introduced in the late 1970s and early 1980s. These point-and-shoot cameras calculated shutter speed, aperture, and focus, leaving photographers free to concentrate on composition.

Camera Digital Revolution

The first digital camera was developed in 1988 but was never sold to the public. It wasn’t until 1991 that Kodak released the Kodak DCS, which was their first in the long line of digital cameras. Other manufacturers quickly followed, and today, Canon, Nikon, Pentax, and other manufacturers offer advanced digital cameras.

Even the most basic point-and-shoot camera now takes higher quality images, and smartphones can easily pull off a high-quality printed photograph. The production and development of digital cameras have continued to increase over the years.

Interestingly enough, despite the move from digital cameras to smartphone cameras, there has been a rising popularity of Polaroid film cameras. In 2004, Epson, a company well known for the photographic printer and ink, introduced the first true mirrorless camera, the RD1.

In partnership with Cosina, Epson developed the RD1, which was another big leap in the development of cameras. These cameras started gaining popularity among enthusiasts, travelers, and street photographers who did not want to carry a bulky DSLR.

The sky is the limit to where cameras will go from here. Now, professional-grade images can be produced with nothing but a smartphone and a selfie stick. It’s fascinating to imagine that just over 200 years ago, photographs as we know them were still experimental. Maybe in 10 years’ time, we’ll have camera eyes capable of producing the highest level of resolution possible.
