How the pinhole camera works

A pinhole camera/camera obscura is the most simple form of photography, made up of a light proof box, light sensitive paper/film and a pin hole. The pin hole will be on the opposite side to where the film will be so when the light is let in through the hole the image from outside will be reflected upside down onto it.



The pinhole acts as the lens as the camera. The smaller the pinhole, the smaller/sharper the point of light that it creates, therefore the image will be more crisp. The paper/film reacts to the light and where the light hits it is exposed and where there is no light the paper remains light. You will then have to develop the photographic paper to see the image.
