#8 Camera Or The Human Eye, It’s All the Same
The camera is a dupe of the human eye. Both have instruments that rely on refraction and lenses to draw images. The pupil uses a diaphragm to have control over the amount of light that enters through the lens, which in the case of the camera is done by the shutter.
Both follow the principle of creating an image with the help of a lens to focus on the light. The fastest lens known till date is of the human eye. They act way faster than any professional camera lenses.
