In the early days of film making there was only the old fashioned film camera. The quite simple process of exposing a piece of plastic that had been coated with light
reactive chemicals to the light that had bounced off the subject to be photographed. The issue with this way of working was that in the field the film maker had no way of checking to see if they had
captured the subject correctly, besides removing the film and having a look. Add to that the fact that film stock was so expensive. This left the photographer with a problem, to do another take
knowing that they could already have it and therefore waste more expensive photo stock.
Because of these problems the digital camera was invented. With a digital screen the film maker could easily access and look through previous images even if they had been taken long before. This allowed the film maker to rapidly see if the shot had been taken correctly.
The invention of the digital memory card also meant that if the film stock had not been exposed properly then the another shot could be taken at no extra cost.
Another advantage was that the film maker did not have to change film all the time. Off course the memory card would have to be replaced at some point, but no way as often as the changing film stock.
Another extra advantage to the digital camera is all the extra controls which can be used for shooting and also editing the picture in camera. All these extra controls give the professional photographer more tools with which to take the perfect picture.
The first Camcorders where how ever poor quality because the technology was not there to produce chips that could record
fine quality. Now that the technology has advanced we now have 4k cameras that produce real clarity in the image.
