Camera History & Parts 

1. Explain the “camera obscura” effect. How is it achieved? 

In a completely dark room, make a tiny hole in one wall. through that hole the light is focused and the outside is projected in the other wall up side down.

2.What invention during the 17th Century helped man get a step closer to creating the modern camera?

In the 17th century, Isaac Newton and Christian Huygens perfected 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 photograph, and the modern camera was born:
A glass lens, a dark box, and film.

4.What do modern digital cameras have in common with Niepce’s camera?

New cameras are very easy to use, just point and shoot. The camera's built-in computer handles focus and exposure so you don't have to. That is what they have in common

5. What do digital cameras use to capture an image?

 Light passes through the lens, into the camera, and exposes the film. And guess what? The end result is still a photograph. That is what they use.

6. What is the difference between the Auto Mode and the Program mode?

 Auto mode- will completely focus on the flash and exposure 

 Program mode- you just point and shoot (take the picture).

7. What is the Portrait mode used for? How does it work?

 Portrait mode is use for blurring out the background so you could mainly focus on the
Most important object. 

8. What is the Sports mode used for? (not just sports) How does it work?

 To freeze the motion of the picture that is being taken at the time.

9. Why should you do a half press on the trigger button?

faster camera response time 
more control over focus
encourages better composition

10. What does this symbol mean? When would you use this?  

no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.

11.What does this symbol mean?

12. What happens to your photo if there is too much light?

Too much light and the picture will be washed out

13. What happens to your photo if there is not enough light?

Not enough light and the picture will be too dark.

 14. What is a “stop.”

The term "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?
 one     

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

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

18. What affect does a shorter shutter speed have?

 less light

19. What does the aperture control?

 You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20. When adjusting the aperture, how can you increase the amount of light?

   larger openings = more light
