How Digital Cameras Have Evolved

By Sean Chandler


Being able to capture images brought the idea of the camera into existence. The ideas for the camera are rooted in early Chinese and Greek history. The first photography was attempted by viewing images through some kind of pin-hole device.

The idea of the camera device was thought to be conceived theologically. It was based on an earlier concept of a Divine power. Cameras today are mostly digital, but they have descended from a long lineage of cameras.

When cameras were first invented, nobody gave a lot of thought to carrying them around. The pin hole version was the first model and after that the devices kept developing. But they were often large and ungainly because, after all, everyone realized that a person sized image was what was going to be captured with it.

In this camera, a static picture was taken by making the best use of available natural elements, and thus the required lighting was effectively created so as to click a picture via the pin-point device. After that, the person whose picture was clicked was displayed on the screen. And this image was manually printed on the then available resources.

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.

The discovery of a substance like gelatin that could allow the images to set and stay permanently was a big leap in the evolution of cameras. But there needed to be a quickness of response to go with this new material and imaging, so a mechanical shutter was invented that could easily be triggered to capture the image desired.

It was after the first kind of film that was invented; the first instrument i.e. the camera was invented successfully. This camera developed in 19tth century was a block shaped instrument, black in color and build with identical technology that is found in its successors.

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.
