The Camera

1. In a dark room, a tiny hole is created in one wall. Light is focused through the hole and the image appears upside down, on the opposite wall and this is known as camera obscura.

2.  The 17th century camera was updated by perfecting the understanding optics and the making of glass lenses. This made the camera more improved than before thanks to Isaac Newton and Christian Huygens.

3. In the 1830s, Niepce added film to the camera which was much more modern at this point in time. During this time, a camera was a glass lens, dark box and film.

4. Niepce's invention still applies to the camera we use today. They both have light pass through the film, into the camera, and expose the film.

5. Now days, we use an electronic sensor called a Ccd instead of using old, plastic film like they did back then.

6. For auto, the camera completely controls flash and exposure. Unlike auto, in program mode, you can control the flash mode and exposure and a few other camera settings.

7. Portait mode is used to blur out the background and focus on the subject only. You can adjust this by using the aperture settings.

8. Sports mode is when you try to freeze motion or fast movement in a photo. It can be used for anything that moves like sports, running, jumping, waves, etc. It's used by using the fastest shutter speed possible on the camera.

9. You should half-press before taking a picture because it will help the camera adjust to settings and you have more control over focus and a faster camera response.

10. This symbol mean there is no flash on. A reason you may not want to use it is because when you use natural light and not flash, the photo is usually more dramatic.

11. This symbol means auto flash. This symbol is enabled if the camera thinks there needs to be more light for the photo.

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

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

14. A stop is a relative change in the brightness of light and is used in every aspect of photography.

15. The new planet with two suns is one stop brighter.

16. The new planet with four suns is two stops brighter.

17. The longer shutter you have, the more light is let in.

18. The shorter shutter you have, the less light is let in.

19. The aperture controls the amount of light let in and can relate to the pupil of a human eye.

20. The way you can control the amount of light coming through, is adjusting the f-stop number and the smaller f-stop's number, the larger the opening, and the larger the opening, the more light is let through.
