The Camera History and Basic Functions
The Camera
1. The "Camera Obscura" effect is an ancient optical device. It is achieved by being inside an completely dark room and then a tiny hole is created on one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.
2. The invention during the 17th Century that helped man get a step closer to creating the modern camera was when Isaac Newton and Christian Huygens perfected the understanding of optics and projecting light onto a wall of a dark chamber.
3. The parts of the first modern camera invented by Niepce were a dark box, a film, and glass lens.
4. Modern digital cameras and Niepce's camera both have something in common. They both have light passing through the lens, into the camera and exposing the film, which is what creates a photograph.
5. Digital cameras use electronic sensor called a CCD to capture an image.
6. The difference between Auto Mode and Program Mode is that when its on Auto Mode, the camera completely controls the flash and exposure. When its on Program Mode, you can usually control flash and a few other camera settings.
7. Portrait Mode is used to attempt to blur out the background. It works when camera will try to use the fastest available lens setting (aperture).
8. Sports Mode is used to freeze motion. It works when the camera will try to use the highest shutter speed possible.
9. In Manual Mode the photographer must set both the shutter and the aperture mode.
10. You should do half press on the trigger button so the camera can know you're almost ready to take a shot and be prepared, triggering the Focus Lock and the Faster Full-Press Response.
11. This symbol means Disabled Flash. You would use this when you don't want to use flash.
12. This symbol means Auto-Flash. You would use this when you want the camera to automatically fire if the camera thinks it needs more light.
13. If there is too much light, your photo will be washed out.
14. If there is not enough light, the photo will be too dark.
15. A "stop" represents a realtive change in the brightness of light.
16. If there are 2 suns instead of one, the new planet would be 1 stop brighter.
17. If there a 4 suns instead of one, the new planet would be 2 stops brighter.
18. A longer shutter of speed has more light.
19. A shorter shutter of speed has less light.
20. The aperture is like a pupil. Before light reaches film, it must pass through an opening called an "Aperture".
21, When adjusting the aperture, you can increase the amount of light by having a larger opening.
