The Camera
1. The camera obscura effect is an optical effect discovered by Greek and Chinese philosophers, and it is achieved by creating a very small hole in the wall of a very dark room and shining a small light through it. when you do this, the outside scene is projected upside down on the wall inside the dark room.
2. When Isaac Newton and Christian Huygens began to understand optics and how to create high-quality lenses in the 17th century, we came one step closer to modern cameras.

3. The first modern camera, created by Niepce, had these parts: a glass lens, a dark box, and film.
4. Modern cameras are similar to Niepce's "modern" camera. They both have light that passes through the lens, into the camera, and exposes the film.
5. Digital cameras use an electronic sensor called CDD to capture images.
6. Auto mode controls flash and exposure, while Program lets you do that yourself. Program is basically just point and shoot but it lets you control more than on Auto mode.
7. Portrait mode is best to use if you want to take a photo of something and blur out the background, and the camera will try to use the fastest lens setting available. You use portrait mode simply by pressing on the button that has a face on it.
8. Sports mode is used when you want to freeze motion. The camera will use the highest lens speed possible.
9. You should half-press the trigger button because when you do that, the camera focuses by itself.
10. That symbol means that you are disabling flash. You would use this when you do not want/need flash.
11. That symbol is auto-flash. This is usually set by default on most camera modes. Your camera will use this when it thinks your photo needs more light.
12. If there is too much light in your photo it will become washed out.
13. If there is not enough light in your photo then it will be too dark.
14. A stop is a relative change in the brightness of light.
15.1 suns brighter
16. 3 suns brighter
17. A longer shutter speed lets more light in.
18. A shorter shutter speed means less light.
19. Aperture controls how much light is being let into the camera.
20. When adjusting the aperture, you can let more light in by making the f-stop number smaller.
