Camera History and Basic Functions

Camera History and Basic Functions 

Part 1

1. The "camera obscura", was a dark room with a hole in one side of the wall, that projected the outside image upside down. This effect is achieved because the whole acted like a lens, reflecting the picture upside down on the opposing wall.
2. The creation of the lens and the understanding of optics, by Isaac Newton and Christian Huygens, helped to get one step closer to the modern camera. 
3. The first modern camera, the Niepce, was a glass lens, a dark box and film.
4. Both the modern and Niepce camera have a lens, film, and is contained in a box sort object. 
5. The modern camera uses digital film, instead of actual physical film.

1. The Auto mode completely controls flash and exposure, Program mode lets you control flash.
2. Portrait mode is used to take photos of an object/person and blur the background.
3. Sports mode is used when someone whats to freeze an image, causing the camera to use the highest stutter speed possible.

Part 3

Part 4

1. The symbol means that flash is disabled, and will not be used when taking a picture.
2. The Auto Symbol is when the camera controls when the flash is used when the photo needs more light.

Part 5

1. Too much light in a picture can wash out the image.
2. When a photo does not have enough light, the image will be too dark.

Part 6

1. "Stop" is used to represent a change is brightness and light.
2. The new planet is 1 stop brighter.
3. If there were four suns, the planet would be 2 steps brighter.

Part 7

1. A longer shutter speed allows the image to have more light.
2. A shorter shutter speed allows the image to have less light.
3. Aperture controls the opening to allow more and less light.
4. You can  control the Aperture by going into the settings of the camera (aka the F Stop.)
