From these inventions, the cameras of today were created. Light is what photography is all about and it is the purpose of the camera. The camera is a light tight box which allows light only to enter when a button is pushed. There are two features on the camera that control the amount of light allowed to expose the film, these are the shutter and aperture. The shutter is located in the camera box, while the aperture can be found in the lens compartment.
Lenses also play a big part in controlling light.
In order for our eyes and cameras to form images light must be controlled in some way. Lenses do so by collecting light rays and aiming them so that they create a clear image. These lenses can also be found inside the lens compartment. Following are two diagrams to show the basic parts of a camera inside and out. Outside Inside Light and the Camera Light is made up of electromagnetic radiation and is part of the electromagnetic spectrum.
