The Camera History and Basic Functions
The Camera
1. The "camera obscura" effect is the latin words for, "dark room". This was the first camera and it is achieved by, you go inside a completely dark room. A tiny hole is then created in one wall. Through the hole light is focused, and projected on the opposite wall to create an image.
2. The invention in the 17th Century that helped man get closer to the modern camera was when Issac Newton and Christian Huygens understood optics and the process of making quality glass lenses.
3. The parts of the first modern camera invented by Niepce was a glass lens, a dark box, and film.
4. Modern digital cameras and Niepce's camera both work the same way. Light passes through the lens, into the camera, and then the image is shown. This technique was used for both types of cameras.
5. Digital cameras use an electronic sensor called a CCD, to capture an image. Then, the photographs are stored on memory devices.
Camera Modes
6. The difference between the Auto Mode and the Program Mode is that with Auto Mode, the camera will completely control flash and exposure. However, Program Mode is automatic-assist. You control flash and the setting instead of the camera.
7. The Portrait mode is used to focus on one thing and blur out the background. The camera uses the fastest lens setting ( aperture ).
8. Sports mode is used to freeze motion, the camera will use the highest shutter speed possible.
9. In Manual Mode, the photographer has to set both the shutter and the aperture.
The Half Press
10. You should do a half press on a trigger button because it creates a better composition, more control over focus, and the camera has a faster response time.
Controlling Flash
11. This symbol means disabled or no flash. You might use this when you want the mood of the photograph to be more dramatic, by only using natural light.
12. This symbol means auto flash. You might use this when you think the image needs more light.
Introduction to Exposure
13. When your photo has too much light, the picture will be washed out.
14. If there is too little light, the picture will be too dark.
The Universal Stop
15. A "stop" is a relative measurement of light.
16. If there are two suns instead of one, the planet is two stops brighter.
17. If there are four suns instead of one, the planet is four stops brighter.
Shutter and Aperture
18. A longer shutter speed means more light in the photo.
19. A shorter shutter speed means less light in the photo.
20. The aperture controls the light that passes through the lens.
21. You can increase the amount of light by opening the aperture more. Larger openings means more light.
