The Camera

1. The camera obsura effect is an optical effect. You can use this effect by being in a dark room that has a hole in the wall where light passes through. The hole acts like the lens of a camera. It focuses on projecting light onto the wall in the dark room.

2. The modern camera came a step closer when Isaac Newton and Christian Huygens made the understanding of optics and the process of making high quality glass lenses perfect.

3. In 1827 Joseph Nicéphore Niépce added film to create the first successful photograph, and the modern camera was born. Just a glass lens, dark box and film.

4. New cameras are very easy to use, just point and shoot. The camera's built-in computer handles focus and do almost everything for you.

5. Digital cameras capture the images with an electronic sensor called a CCD. Photographs are stored on reusable computer memory devices. Modern cameras are cheaper and better environmentally.

6. In program mode you have to set your own setting and focus your camera, but in auto mode the camera does everything for you. 

7. The portrait setting is used to blur out the background and focus on the center of the photo. To take a photo with this setting the camera uses the fastest lens available.

8. The sports setting on a camera is used To freeze motion, camera will use the highest shutter speed possible. 

9. If the subject is somewhat off-center, the auto-focus may be fooled. A half-press will tell the camera that you're almost ready to take a shot and to be prepared.

10. The symbol means no flash and should use it when you don't want to use the flash in the photo you are taking.

11. The symbol means auto flash and the camera turns it on when you are in a dark area or there is a shadow. 

12. There is too much light the picture will be washed out.

13. When there is not enough light the picture will be to dark. 

14. A stop is used to represent the change in the brightness or light.

15. One stop brighter if there are two suns instead of one.

16. There are two stops brighter if there are four suns instead two.

17. Longer shutter speeds allows more light.

18. Shorter shutter speeds allow less light.

19. The aperture controls the pupil or opening of the camera.

20. When adjusting the aperture you can adjust the amount of light by setting the F stop. The bigger the opening the more light comes in to the photograph.
