How does light travel through a camera?

Answer 1

The Lens is the image-forming device on a camera. The lens bends light rays to project an image onto a light sensitive medium, which may be any of several forms, including film, sensitized glass plate, or electronic sensor.

The Diaphragm is a variable opening which controls the quantity (brightness) of light falling on the light sensitive medium.

The Shutter controls the length of time light is permitted to fall on the light sensitive medium. It can take many forms, but usually has some method for precision adjustment of the time it is open.

Light passing through the lens, aperture, and (when open) the shutter forms an image of specific brightness for a specific duration on the light sensitive medium.

Light also passes through a viewfinder system, which may be a part of the optical system of the camera, or separate from it. In the most complex cameras, some of the light passing through the lens is diverted into a viewfinder by means of a mirror or prism. By using some of the same light passing into the camera, these systems permit the user to see essentially what the camera is seeing.

Answer 2

Light enters the camera through the camera lens, which then passes through the aperture and shutter. The light then hits the image sensor, where it is converted into an electronic signal that forms the image. This image is then processed and stored in the camera's memory.

Answer 3

I found this picture of the light rays and it is a good example of the Incident rays making the focal point!!

Answer 4

The light bends.
