The Camera

1. The "camera obscura"effect is known as the first camera. By creating a small hole located in one wall of a dark room, the light focuses through the hole and projects the outside scene upside down on the opposite wall.

2. During the 17th century, Isaac Newton and Christian Huygens invented high quality glass lenses that brought us one step closer to the modern camera.

3. The first modern camera invented by Niepce included a glass lens, a dark box, and film.

4. Modern digital cameras are similar to Niepce's in the way that light passes into the camera through the lens, and reveals the film, which results in a photograph.

5. Digital cameras use digital film that is called a CCD and can be stored on resizable computer memory devices.

6. Auto mode means that the camera will control the flash, where as if you're in program you can control the flash yourself.

7. Portrait mode is used to blur the background in a photo by playing with the aperture.

8. Sports mode is used to freeze the motion of the subject you are shooting. It applies the settings, mainly the highest possible shutter speed, for you and adjusts itself to the appropriate lighting.

9. Half pressing the trigger button focuses the image before you shoot it.

10. This symbol means that there will be no flash, so the natural light is used in the picture.

11.This symbol means auto flash, and it means that the camera controls the flash for you.

12. If there is too much light the photo will be washed out.

13. If there is not enough light, the photo will be too dark.

14. The word 'stop' represents a relative change in the lighting/brightness of a photo.

15. It would be one stop brighter.

16. The new pant would be two stops brighter.

17. The longer the shutter speed, the longer the shutter stays open to allow light in, meaning the photo will be brighter.

18. The shorter the shutter speed, the quicker the shutter stays open to allow light in, meaning the photo will appear darker.

19. Aperture decides the amount of light let into the photo.

20. By making the aperture opening larger, more light will be let into the photo.
