the camera history and basic functions

The Beginner's Guide to Photography        the camera

THE CAMERA 

1. the camera obscura effect is the first camera. it is achieved by using a box and creating a small hole where light is focused through. then the scene is projected upside down on a different wall.


2. Isaac Newton and Christian Huygens created a higher quality lens.

3. Joseph Nicéphore Niépce added the "film".

4. cameras used now still work in the same way older cameras did. (light passing through the lens, into the camera, and exposing the film)

5. digital cameras capture the images with an electronic sensor called a CCD.

CAMERA MODES

6. with auto mode you have to air for the flash and exposure while with the program mode you plainly point and shoot.

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

8. the sports mode is used to freeze the current motion. the camera will use the highest shutter speed.

THE HALF PRESS

9. the half press tells the camera to wait just a while longer so the photographer can steady.

CONTROLLING FLASH

10. disabled flash: no flash; to create a dramatic mood.
11. auto-flash: when the camera thinks the scene needs more light

INTRODUCTION TO EXPOSURE

12. if there is too much light it will not look real.
13. if there is not enough light it will not look real.

THE UNIVERSAL STOP

14. a stop is a relative change in light.
15. if two suns:1
16. if four suns:2

SHUTTERS AND APERTURES

17. longer shutter speeds = more light

18. shorter shutter speeds = less light

19. the aperture controls the amount of light.
