What is a camera?
If you position a piece of white paper and a piece of foil with a small, pin-hole size opening so that the sun shines through the opening and on to the paper, you will see an image of the sun on the paper.
That's physics.
Put them in a box and the same thing happens. If the paper onto which the light is projected is "light-sensitive" you have a pinhole camera.
That's chemistry.
So..........a camera is a light-tight device (box) with an opening at one side to let light in and a means of capturing the projected image created by the light on the other side.
Digital cameras capture this image with a sensor. Earlier cameras used film to capture the image.
It all began a long time ago
This phenomenon was observed by Aristotle (384-322 BCE) in ancient Greece. Camera Obscura. Latin for "darkened room". |
Lenses and mirrors were added during the Renaissance. |
The first cameras captured the image on a metal plate. They were called daguerreotypes. |
Also called tin types. Who is this person? |
