Photography relates to the action of light on sensitive bodies in the production of pictures, the fixation of images.

"Photography" is derived from the Greek words photos ("light") and graphein ("to draw") The word was first used by the scientist Sir John F.W. Herschel in 1839. It is a method of recording images by the action of light, or related radiation, on a sensitive material.

A camera is a device that records/stores images. The term camera comes from the camera obscura (Latin for "dark

chamber"), an early mechanism for projecting Images. The still camera takes one photo each time the user presses the

shutter button.

The Aperture

Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
