2.What invention during the 17th Century helped man get a step closer to creating the modern camera?
    In the 17th century, the modern camera came one step closer 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?
   In 1827 Joseph Nicephore Nicepce added the final touch. he added *film* to create the first successful photograph, with a glass lens and a dark box.
4.What do modern digital cameras have in common with Niepce's camera?
   They have the same things an older camera has.
5.What do digital cameras use to capture an image?
   Light passes through the lens, into the camera, and exposes the film. The result is a photograph.
6.What is the difference between the Auto Mode and the Program Mode?
   Auto mode will completely control flash and exposure, Program Mode is automatic assist and will just point and shoot.
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?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?
    A half press will tell the camera that you're almost ready to take a shot and to be prepared, triggering for the focus lock and a faster full-press response.
10.What does this symbol mean?
     This symbol means there is no flash.
11.What does this symbol mean?

     The result will not look like "real life".
13.What happens to your photo if there is not enough light?
     The result will not look like "real life".
14.What is a "stop"?

15.How many stops brighter is the new planet if there are two sons instead of one?
     One stop brighter.
16.How many stops brighter is the new planet if there are four sons instead of two?
     Two stops brighter.
17.What affect does a longer shutter speed have?
     More Light
18.What affect does a shorter shutter speed have?
     Less light
19.What does the aperture control?
     Before light reaches film, it must pass through an opening.
20.When adjusting the aperture, how can you increase the amount of light?
     If you make the aperture smaller.
