The camera

1. Explain the “camera obscura” effect. How is it achieved?
Inside a completely dark room, a tiny hole is created in one wall. Through the hole 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?
Lense and optics

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

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.  The end result was still a photograph.

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

6. What is the difference between the Auto Mode and the Program mode?
Auto mode focused for you based on your location, while program mode is where you have to set everything up. 

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 (aperture).

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

9. Why should you do a half press on the trigger button?
If the subject is somewhat off-centre, the auto-focus may be fooled. You have probably seen this effect many times before. A half-press will tell the camera that you're almost ready to take a shot and to be prepared
