THE CAMERAS HISTORY

                                            The Camera
1. Explain the "camera obscure" effect. How is it achieved?- In ancient tines, Greek and Chinese philosophers discovered a curious optical effect, and it worked like this: Inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.

2. What invention during the 17th century helped man get a step closer to creating the modern camera?- In the 17th century, the modern ca,era came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics.

3. What were the parts of the first modern camera invented by Niepce?- A glass lens, a dark box, and film.

4. What do modern digital cameras have in common with Niepce camera?- Light passes through the lens, into the camera, and exposes the film.


5. What do digital cameras use to capture an image?- electronic sensor called a CCD.

CAMERA MODES

6. What is the difference between the Auto Mode and the Program mode?- Auto mode will completely control the cameras flash and exposure and the program mode is just point and shoot.
 

7.  Portrait mode is used to attempt to blur out the background, camera will try to use the fastest available lens setting.

8. To freeze motion, camera will use the highest shutter speed possible

THE HALF PRESS

9. Because the half press makes the camera do a focus lock on the object that your trying to take a picture of.

CONTROLLING FLASH

10. (1st question) it means that there is no flash.

11. Auto flash is enabled by default and will automatically fire if the camera thinks it needs more light.

INTRODUCTION EXPOSURE

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

13. If there is not enough light then the picture will be to dark.

THE UNIVERSAL STOP

14. The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.

 15. The light intensity will increase by one stop.

16. The light intensity will increase by two.

SHUTTERS AND APERTURE

17.  The effect of long shutter speeds leads up to more light.

18.  The effect of shorter shutter speed leads up to less light.

19.  The brightness because the aperture is just like a pupil.

20.  Smaller F-stops numbers= larger openings.
