The Camera

1. The "Camera Obscura" effect is achieved by creating a dark room, and shining light onto the wall of the dark chamber.
2. Lenses and optics were invented in the 17th century, this helped the camera take one step closer into the reach of mankind.
3. The parts of the first modern camera were a glass lens, a dark box and film, invented by Joseph Nicéphore Niépce.
4. Modern cameras contain film (or digital film), a dark box, and a lens, just like Niépce's.
5. Digital cameras use an electronic sensor, called CCD, that replaces the old plastic film.
6. The difference between Auto Mode and Program Mode is that Auto Mode completely controls the exposure and flash, whereas the Program Mode will let you take the reigns of flash and exposure.
7. The Portrait Mode is used for blurring out the background, so you can focus on the main part of the photo, it does this by using the fastest available lens setting (aperture). 
8. The Sports Mode is used for freezing the motion, it does this by using the highest shutter speed.
9. You should do a half press on the trigger button because it gives you more control over focus, as well as faster camera response and it even encourages better composition.

10.This symbol means that there is NO flash, you'd use this when you want natural light, or maybe your preference is no flash. 

11. This symbol means that the camera will automatically flash if it feels the picture needs more light. It's called Auto-Flash, it's enabled by default.
12. If your photo has too much light, it will be washed out.
13. If your picture has too little light, your photo will be too dark.
14. A stop is something that represents a relative change in light.
15. If there are two suns instead of one, it means there was one stop.
16. If there are four suns instead of two, that means that there was two stops.
17. The affect of a longer shutter speed is that you'll have more light in your photo.
18. The affect of a shorter shutter speed is that you'll have less light in your photo.
19. The aperture controls the amount of light coming into the lens. 
20. When adjusting the aperture, you can increase the amount of light by making smaller F-stops, which makes more light come through.
