The Camera History

CAMERA HISTORY 

1. The "camera obscura" effect is a latin meaning "dark room" was the first camera. The effect was achieved by being in a complete dark room with a tiny hole in one wall, through it the light gets focused and on the other side it becomes projected. 

2. In the 17th century the invention that got man closer to modern camera was the understanding of optics and the process of making high quality glass lens perfected by Sir Isaac Newton and Christian Huygens. 

3. Later it became smaller, and portable but in 1827 Niepce added a film to create the first photo. After that the first modern camera was born a glass lens, dark box, and film. 

4. The common things that a modern camera has with Niepce's modern camera is that fact that they both work the same, light passes through lens, into the camera, and exposes the film, then tah-dah a photo. 

5. Digital cameras use an electric sensor called CCD so that photos are stored on reusable computer devices, resulting it being cheaper, and environmentally friendly. 

CAMERA MODES 

6. The difference between Auto mode and Program mode is Auto fully controls the flash, and exposure. Program is manually and usually control flash and other settings too. 

7. The portrait mode is used to blur out the background, and uses the fastest lens setting (aperture).

8. Sports mode is to freeze motion, camera uses the highest shutter speed. 

HALF PRESS

9. You should half press on the trigger button because its easier and the camera tells you when it's ready. 

CONTROLLING FLASH 

10. The symbol means flash, and its used when the area is dark and photographer needs more light. 

11. The symbol means no flash and they use it when the photographer want a more dramatic photo so natural light is used.

INTRO TO EXPOSURE 

12. The thing that happens to your photo when there is too much light is that the picture will look washed out. 

13. What happens when there is not enough the picture will look too dark. 

THE UNIVERSAL STOP

14. The term 'stop' is used in every aspect of photography because it represents a relative change in the brightness of light. 

15. You have to make it one stop brighter 

16. You have make it 2 stops brighter 

SHUTTERS AND APERTURE 

17. The affects of longer shutter speed is that it brings more light

18. the affects of a shorter shutter speed is that it gives out less light

19. the aperture controls the amount of light coming into the camera  which is like a little hole.

20. when adjusting the aperture you increase the openings, smaller the f-stops and equals a larger openings and larger the openings the more light.
