Camera Parts and History

The camera obscura effect is created by having a dark space with a tiny hole in one wall through that hole light is focused, the scene outside is projected.

The invention of high quality glass lens by Isaac Newton and Christian Huygens helped with creation of the modern camera.
The parts of the first were modern camera were: film, a glass lens, and a dark box.
Digital cameras use a lens which light passes through into the camera and exposes a film.
Auto mode and Program mode are very similar they are both point and shoot modes.
Portrait mode is used to blur out the background in the easiest way possible.
Sports mode is use to freeze motion, the camera using the quickest shutter speed.
This symbol means the flash is disabled. Photos can be made be dramatic with natural light.

This symbol means auto flash. If the camera thinks the photo needs more light the camera will shoot the flash.
If there is too much exposure in a photo the picture will be washed out if there is not enough exposure the picture will turn out too dark.
The systems of aperture, shutter, and film settings are all divided up into "stops".
The planet in the photograph is one stops brighter.
A longer shutter speed will make the photo brighter and a shorter shutter speed will make the photo darker and if it is an action photo will make the photo brighter.
Before the light reaches the film it must pass through a pupil like hole called the aperture or F-stop.
Smaller F-stop openings=larger openings which=more light.
