The CCDs
Digital Photography, is something which has taken the world by storm. It has redefined photography. The heart of the digital camera being the Charge Coupled Devices, a.k.a CCD, invented by Smith and Boyle way back in 1969. These are the "sensors" which we are talking here which makes Digital Photography possible. These act as the "film" in the digital cameras where the image is captured.
Well we can get to the nitty gritties of the science behind the Digital Cameras and CCDs later, but the fact is that it has allowed amateurs to develop their photography skills at a much lower price.
Digital Cameras give the "Instant Gratification", i.e. one does not have to wait for the roll of the film in the camera to be shot completely and then given to a photo lab for processing and at the end of which, one finds what he had clicked. Now this process in a film camera could span anywhere between a day to months. Now as an amateur, when I am learning photography, I would like to see the outcome of what I shot as soon as possible, more so if I have the penchant to improve my skills. Seeing the shot immediately, lets me understand my mistakes with the surroundings, lighting, my camera settings everything fresh in my mind. In the analog world, I would hardly remember how the lighting was or what was the settings on my camera etc., when I would see the outcome. I think this is the one main thing which distinguishes Digital photography from Film era.
But as we always have, the purists still claim that Film photography is the best. Well that is their opinion, either due to the fact that are already masters in this art, and they do not need the instant gratification, or they just resist the new developments in technology.
