A camera is a essentially a black box with a tiny hole to let light in.
It's possible to make a camera out of a cardboard box ; cameras as we know them are just a more sophisticated version of a simple concept.
It's possible to make a camera out of a cardboard box (pinhole photography), a camera with a lens is just a more sophisticated version of a very simple concept.
There are four elements to a camera and understanding them is key to understanding how your camera works,
The first is the lens ; where the light comes in
The second is the aperture ; which is the size of the hole inside the lens (more on this later)
The third is the shutter ; which is a door that opens and closes for a given amount of time
The fourth is the sensor (or film in traditional photography) ; this is where the image is recorded
The sensor or film need the right amount of light to record the right exposure. It's a bit like Goldilocks, the amount of light has to be 'just right' for a good photo.
We can manipulate how much light gets in and for how long - and understanding how to use your camera's settings is the key to technical ability and creative control.
