The Historic Timeline Of Digital Cameras

The Chinese and the Greeks may have been the first ones who thought of capturing a still image using a pin hole device. This is something that has intrigued many cultures since those early days of photography and has kept evolving.

Since the image of a person or animal had a divine significance in the scheme of things, the camera has had something of a theological background. To capture an image was a sacred occupation, and some cultures, such as the Amish, still forbid it to this very day. But the camera has continued to evolve, and today's digital technology has continued that evolution from a long line of more primitive attempts.

The pin-hole camera technology that was used allowed creative thinkers to come up with the idea of capturing still pictures. This led to a primitive version of a camera. The first known record of a camera that could capture imagoes was so large it was not transportable. It was large enough only to allow individuals to be photographed.

The available elements in nature made it possible to capture images with this primitive camera. The sun provided the light that went through the pin-hole. The image of the person inside was displayed on a screen, and then hand copied onto available materials.

These sorts of early cameras were really just meant as entertainment. They got a bit more sophisticated when darkening chemicals were understood which would allow the images to be seen when placed under a light. They could also fade very easily though and so were not very permanent. Cameras also got more portable as inventors got more creative.

A different substance was used at this point resulting in a more successful lasting captured picture. A plate containing gelatin was used by later scientists that enabled a higher speed image capture. This greatly improved the results.

The first recognizable camera was made after a form of film was developed. In the nineteenth century, a black block shaped device was used. It had the same capturing ability that became available with later, more technologically advanced cameras.

Cameras have evolved a great deal over time and have become more available to the consumer. The latest technologies are mostly digital. These digital cameras have many features including video, and ability to transfer the data to storage media or a computer.
