PhotoJ - "The Camera"

1. The ''camera obscura'' was the first camera used by the greek and chinese philosophers. It simply means ''dark room'' and it is a completely darkened room with just a small hole which acted like a lens. This ''lens'' is focusing and projecting light on the wall of the dark room.

2. In the 17th century Isaac Newton and Christian Huygens ''perfected the understanding'' of high quality lenses and optics. So they started building them by themselves. That was an invention which helped man get closer to creating modern cameras.

3. In 1827 Niepce invented the so called ''film'' to create the first successful photograph so that the modern camera was born.


4. Modern cameras work the same as their ancestor from Niepce: ''Light passes through the lens, into the camera, and exposes the film''.

5. Digital cameras capture the pictures with an electronic sensor called CCD so photographs are stored on reusable computer memory devices.

6. In Auto mode the camera will completely control flash and exposure and Program mode is an automatic-assist, that means just point and shoot.

7. The Portrait mode is used to blur out the background so the camera will try to use the fastest available lens setting (aperture).

8. You use the Sports mode when you want to freeze motion. The camera will use the highest shutter speed possible.

9. Using the Half-Press has faster camera response time, more control over focus and it encourages better composition.

10. It stand for Disabled Flash, which just means there is no flash used. And you use it when the natural light looks more dramatic and better.

11. This symbol is calles Auto-Flash and it means that the camera enables if flash should be used or not. 

12. If there is too much light, the picture will look washed out.

13. And if there is not enough light, the picture will be too dark.

14. A ''Stop'' is a relative change in the brightness of light.

15. It is one step brighter.

16. It is two steps brighter.

17. A longer shutter speed means more light.

18. Shorter shutter speeds mean less light.

19. The aperture is like a pupil and it controls how large or small the opening is the light passes through.

20. You have to reduce the F-Stops numbers because the smaller the numbers, the larger are the openings.
