How Digital Cameras Came to Be

If you have walked around in the streets of China you have most probably come across the many electronics shops that offer digital photo taking gadgets on wholesale; or even anywhere around the world you are sure to find a poster saying ‘digital cameras from China on wholesale’ stuck on a window. Have you ever taken the time though to think about digital cameras, outside of the China wholesale context; and considered how they came to be?

The history of the camera traces its roots all the way back to the time of the Chinese and the Greeks; with the main idea of capturing images being conceptualized by the pin-hole photograph device. The pin-hole photograph device was just the first step that was taken towards the cameras we have today, with it being the inspiration for the invention of the earliest picture taking device.

This first picture taking device was just an enlarged version of the pinhole design that accommodated persons in side itself. It made use of the elements of nature, which provided lighting that was captured through a pinhole. This light made it possible for the image of an individual to be displayed on a screen, and then the image would be copied to other available materials manually. This form of the photo capturing device did not take the issue of portability into account however, since it was made for entertainment purposes and as such portability was not really an issue.

The above photo capturing device was then succeeded by one that made use of design skills of inventors of that time. This version made use of certain darkening chemicals. These darkening chemicals only revealed themselves under some required lighting to view the images and as such the images did not last long. This attempt was however followed up by a more successful one.

Photo capturing device inventors applied device designs that enabled a faster mechanism of capturing images with improved standards of image results. This new mechanism made use of gelatinous plating which provided for longer lasting images. The new mechanism however needed a capturing system that could meet the newer standards. This resulted in a shutter being added to the device. The shutter observed a mechanical response when triggered.

The above mentioned versions of picture taking devices are nowhere near the present day gadgets that we know but, the version that succeeded the gelatinous plating device is more recognizable. This photo gadget was a black block shaped device, commonly seen in old movies; with the same capturing technology made use of by present day cameras. This block shaped device then evolved to the handheld devices that had to have their film processed in order to produce hard copy photos. All the above mentioned gadget design modifications finally gave way to the digital devices we use today.

It is not only digital cameras that are around today but many versions of the gadget, each with its own advantage over the other; with common features offered being video capturing capabilities along with good picture storage devices loading facilities.
