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

                Isaac Newton and Christian Huygens created high quality glass lenses during the 17th century which helped man get a step closer to creating the modern camera.

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

                 The first parts were a glass lens, a dark box, and film.

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

                   Modern digital cameras still work the same way as Niepce's camera did by passing light through the lens, into the camera, and exposes the film.

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

                    Digital cameras use an electronic sensor called CCD.

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

                  Auto mode will completely control flash and exposure while Program mode is an automatic-assist, just point and shoot.

    

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

                Portrait mode is used for focusing on a certain object while the background is blurred, and the camera will try the fastest available lens setting (aperture).

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

                Sports mode is used to freeze motion, camera will use the highest shutter speed possible.

 

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

            You should do a half press on the trigger button so you the camera can focus lock.

 

10. What does this symbol mean and when would you use it?

15. How many stops brighter is the new planet if there are two suns instead of one?

               The new planet would be one stops brighter.

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

               The new planet would be two stops brighter.

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

                A longer shutter speed means you'll have more light in your photo

18. What affect does a shorter shutter speed have?

                 A shorter shutter speed means you'll have less light in your picture.

19. What does the aperture control?

                  The aperture controls the amount of light you'll let into your photo.

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

                   You can increase the amount of light by adjusting your aperture opening to a larger opening.
