Question

Which of the following has a longer integration time (can collect light for a longer period

of time) than the human eye?

a. photographic film
b. photographic plates
c. a CCD (charge coupled device)
d. all of the above (a through c)
e. none of the above

Answer 1

d. all of the above (a through c)

Step-by-step explanation:

Photographic film, Photographic plates and a charged couple device all have longer integration time than the human eye.

The eye optimizes the time interval during which light energy is accumulated until a picture is sent to the brain. This interval is called the "time of integration" and is typically 0.1 sec; for low-light levels, it increases to perhaps 0.2 sec.
