The Camera

1. Explain the “camera obscura” effect. How is it achieved?
Inside a dark room a tiny hole is created in one wall. Light focuses through the hole and the outside scene is projected. 

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

3. What were the parts of the first modern camera invented by Niepce?
It started with the camera obscura, then glass lenses were added and then Niepce finished the first camera by adding film.

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

5. What do digital cameras use to capture an image?
They use digital film, called a CDD which stores the pictures on a reusable camera device. 

6. What is the difference between the Auto Mode and the Program mode?
In auto mode the camera will completely control flash and exposure. In program mode you can control the flash and other settings.

7. What is the Portrait mode used for? How does it work?
It is used to blur out the background of the subject and the camera will use the fastest lens possible to take this photo. 

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

9. Why should you do a half press on the trigger button?
It gives you faster camera response time and allows you to have more control over the focus.

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?

The opening where the light passes through 

20. When adjusting the aperture, how can you increase t
