The Camera
1. "Camera obscura" means "dark room" in Latin. It is achieved by going in a completely dark room and and creating a tiny hole in one wall. The light from the hole is focused and the scene from outside is projected on the other wall.
2. In the 17th century, Isaac Newton and Christian Huygens perfected how to create glass lenses and understand optics which brought man one step closer to creating the modern camera.
3. Niepce invented film, creating the first modern camera.
4. In both modern digital cameras and Niepce's camera, light passes through the lens, into the camera, and exposes the film, which creates a photo.
5. To capture an image, digital cameras use an electronic sensor called a CCD.
6. With Auto Mode, everything is controlled and done by the camera. With Program Mode, the camera will assist you but you will still have control over some camera settings such as flash.
7. Portrait Mode is used for taking someones picture by attempting to blur out the background using the fastest available lens setting.
8. Sports Mode is used to take photos while something or someone is moving. To try and freeze the motion, cameras will use the highest available shutter speed
9. In Manual Mode, the photographer must set the shutter and aperture mode.
10. You should do a half press on the trigger button because it helps with faster camera response time, more control over focus, and encourages better composition.
11. That symbol means Disabled Flash. You can use this if you only want to use the natural light for a more dramatic photo.
12. That symbol means Auto Flash. This is often the default on cameras and it might be used if the camera thinks that more light is needed.
13. If there is too much light the photo will be washed out.
14. If there is not enough light the photo will be too dark.
15. A "stop" is a relative measurement of light.
16. If there were two suns, the planet would be 1 stop brighter.
17. If there were four suns instead of two, the planet would be 2 stops brighter.
18. A longer shutter speed allows more light to come in.
19. A shorter shutter speed doesn't allow as much light to come in.
20. The aperture is like a pupil. It controls the light that goes into the camera.
21. To increase the amount of light you can make the opening of the aperture larger. You can do that by setting the aperture to a smaller F-stop number.
