Question

In explaining the differences between analog and digital photography, highlight the aspects of "channels" that make digital photography different from analog photography.

Explain if RFID can fully automate the player rating process to a micro level of detail, or not. If so, how?

Answer 1

Answer:-

It has become fairly common to describe film photography as 'analogue', to differentiate it from digital photography. In the sense being used here, analogue refers to a signal where the output is proportional to the input. A light meter is a good example of an analog instrument. Light falling on a photocell generates an electrical current which moves a needle across a scale. The brighter the light, the greater the movement.

On this basis, the sensor in a digital camera is also analog. Each of the many millions of pixels which make up the sensor is a light-sensitive photocell which generates a tiny electrical current in response to light. The brighter the light, the stronger the current. Digital only comes into play when the brightness levels are coded into the binary system (the language of computers) to create an image file.

To avoid the confusion of analogue and digital, the French use the word 'argentic' to describe non-digital photography. Argentic means silver and is used because of the silver halide crystals that make up the film emulsion.
