Question

What is the amount of light that passes through the lens and reaches the digital sensor called?

Answer 1

Answer:

"Aperture" seems to be the right answer.

Explanation:

• The intensity of light rays that enters an electronic camera sensor is limited either by an aperture. This same diameter would be determined by f-stops.
• This opens with a smaller f-stop level which accommodates sufficient light to something like the sensor. Relatively high f-stop amounts reduce their aperture of the lenses so that less beam moves.
