Lecture 7:
We begin with a light tight box to hold the film/sensor and carry it around from subject to subject.
The shutter controls when the light enters the camera and for how long it enters. A good camera will have some way of adjusting the time the shutter is open plus there has to be some type of release for the shutter.
The lens lets in light. The larger the lens the more light. The lens also effects how large the image appears based on the focal length of the lens.
The aperture is located in the lens and is a set of leaf like piece of metal that can change the size of the hole that lets in light. We do not actually need a lens to focus an image if we have a small enough hole to let in the light.
