Camera History

1. The "Camera Obscura" was created when ancient philosophers discovered an optical effect, when in a dark room there was a small hole that focused light and was reflected on the opposite wall upside-down.  

2.The step that made closer way to getting the modern camera was when Isaac Newton and Christian Huygens perfected their understanding of optics and the process of making high quality glass lends.

3.The first camera parts invented by Niepce were the glass lends,a dark box, and a film.

4.They both have the same steps, light passes through the lens, into the camera, and exposes the film and you finally get a photograph.

5. This is what digital cameras use to capture an image, photographs are stored on reusable computer memory devices.

6. The difference between a Auto Mode and Program mode is that in program mode you can adjust the  flash and few other camera settings.

7.The portrait mode is used to attempt to blur out the background. The camera will try to use the fastest available lends setting.

8. The sport mode is used to  freeze motion, the camera will use the highest shutter speed possible.

9. You should do the half press on the rigger button because it is easier,thee camera will attempt to lock focus on the subject and the focus lock allows the photographer to freeze the point of focus before taking the picture.

10.That symbol means there is no flash.

11. This symbol means that the camera will fire if it thinks it needs more light.

12. If there is too much light, the picture will be wasted.

13. I there is not enough light then the picture will be too dark.

14. "Stop" means that there is a relative change in the brightness of the light.

15. It would be 4 stops brighter.

16. It would be 16 stops brighter.

17. For longer shutter speed you get more light.

18. For shorter shutter speed you get less light.

19. The aperture controls how much light goes in the camera.

20. To increase the amount of light the aperture has to be more open.
