In the past twenty years, most of the main technological breakthroughs in consumer electronics have been built around the very same basic method: converting conventional analog data (represented by a fluctuating wave) into digital information (binary data represented by ones and zeros, or bits). This fundamental shift in technologies has changed how we manage visual and audio data — it fully redefined what is probable.
The digital camera is one of the most notable examples of this shift because it is so genuinely various from its predecessor. Conventional film cameras depend entirely on chemical and mechanical processes — you don’t require any electricity whatsoever to operate them, other than for a flash. On the other hand, all digital cameras have a built-in personal computer, and all of them record images electronically.
The new approach has been enormously profitable. Since film typically provides far better picture quality, digital cameras have not completely replaced conventional cameras. But, as digital imaging technology has improved, and costs dramatically decreased, digital cameras have quickly grow to be more well-known.
