Question 1 Report

what part of the camera corresponds to the iris of the eye?
Answer Details
The part of the camera that corresponds to the iris of the eye is the diaphragm. Just like the iris controls the amount of light entering the eye, the diaphragm controls the amount of light entering the camera. It is a circular opening in the camera lens that can be adjusted to vary the size of the aperture. When the diaphragm is wider, more light enters the camera, and when it is narrower, less light enters. This helps control the depth of field and the amount of light that hits the camera's sensor or film.
