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

Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lens.

3. What were the parts of the first modern camera invented by Niepce?

He added film, glass lens, and a dark box.

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

Light passes through the lens, into the camera and exposes the film.

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

It uses an electronic sensor called a CCD.

Camera Modes

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

On the auto the camera will control the flash and exposure. Program is automatic-assist, you can control flash and other camera settings.

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

To attempt to blur out the background, camera will try to use the fastest available lens setting. 

8. What is the Sports mode used for? How does it work?

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

The Half Press

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

To get the camera to focus and it'll tell you when its ready for the shoot.

Controlling Flash

10. What is this symbol mean? When would you use it?

Means that there is no flash. When there is enough light in the room.

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

less light.

19. What does the aperture control?

controls the light.

20. When adjusting the aperture, how can you increase the amount of light?
