Camera History!

1. Explain the “camera obscura” effect. How is it achieved? They created a hole in a dark room, through the hole light is focused and the outside scene is projected.

2. What invention during the 17th Century helped man get a step closer to creating the modern camera? When Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.

3. What were the parts of the first modern camera invented by Niepce? He added film to create the first successful camera.

4.What do modern digital cameras have in common with Niepce’s camera? they still do the same thing but the modern camera is cheaper.

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

6. What is the difference between the Auto Mode and the Program mode? On a Program Mode you can usully control flash and other camera settings and on a Auto Mode you can't.

7. What is the Portrait mode used for? How does it work? The Portrait mode is used to make the background blurry. and it works by the camera trying to use the fastest lenses.

8. What is the Sports mode used for? (not just sports) How does it work? the Sport mode is used to freeze motion, the camera will used the highest shutter speed possible.

9. Why should you do a half press on the trigger button? For more control over focus, and faster camera time.

10. What does this symbol mean? This symbol means that there's no flash.

 When would you use this? You would use this when the natural light is more dramatic.

11.What does this symbol mean? Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.

12. What happens to your photo if there is too much light? If there's to much light the picture will be washed out.

13. What happens to your photo if there is not enough light? If there's not enough light the picture will be too dark.

14. What is a “stop.” A "stop" is used in every aspect of photography to represent a relative change in the brightness of light.

15. How many stops brighter is the new planet if there are two sons instead of one? 1 stop brighter.

16. How many stops brighter is the new planet if there are four sons instead of two? 2 stops brighter.

17. What affect does a longer shutter speed of have? A longer shutter speed has more light.

18. What affect does a shorter shutter speed have? A shorter speed has less light.

19. What does the aperture control? The aperture is like a pupil. It controls the light.

20. When adjusting the aperture, how can you increase the amount of light? It does so by closing up to restrict light, and opening up to let it through.
