The Camera

1 - Q; Explain the "camera obscura" effect. How is it achieved?
1 - A; It's a hole in a wall that acts as a lens, projecting light into a dark room.

2 - Q; What invention during the 17th Century helped man get a step closer to creating the modern camera?
2 - A; Issac Newton and Christian Hyugens perfected the lens.

3 - Q; What were the parts of the first modern camera invented by Niepce?
3 - A; The film that was places in the camera, which he considered to be his 'Final Touch'.

4 - Q; What do modern digital cameras have in common with Niepce's camera?
4 - A; The light passing through the lens into the camera that hits the film and creates the image.

5 - Q; What do digital cameras use to capture an image?
5 - A; Digital cameras get their photos with an electronic sensor called a CCD, that acts kind of like a digital film.

6 - Q; What is the difference between Auto Mode and Program Mode?
6 - A; Auto Mode is fully automatic and Program Mode is the manual, default for most modern cameras. 

7 - Q; What is the Portrait Mode used for? How does it work?
7 - A; This is used to take a picture of one specific thing, blurring out the background to put more attention on the subject. 

8 - Q; What is Sports Mode used for? (Not just sports) How does it work?
8 - A; This is used to freeze motion and the camera will use it's highest shutter speed possible to capture the photo. 

9 - Q; Why should you do a half press on the trigger button?
9 - A; Pointing the camera at the subject and then doing the "half-press", should focus on your subject and assure you that your photo should be in full focus.

10 - Q; What does this symbol mean? When would you use it? (Image on Mr. Reeves' website.)
10 - A; Disabled Flash means "No Flash". You should use this when you already have enough light in the room, or you want to have a more dramatic picture and want to use the natural lighting.

11 - Q; What does this symbol mean? When would you use it? (Image on Mr. Reeves' website.)
11 - A; Auto Flash means exactly what it says, the flash is automatic. It is enabled by default and will automatically ,ale the flash of light if the camera deems necessary.

12 - Q; What happens to your photo if there is too much light?
12 - A; If your photo has too much light, it will probably be too bright and you probably won't be able to see the image.

13 - Q; What happens to your photo is there is not enough light?
13 - A; If the photo is too dark, same thing as if it were too bright, it would probably be so dark that you couldn't see the image in the photo.

14 - Q; What is a "STOP"?
14 - A; The term "Stop" in photography terms is to represent a relative change in luminosity. 

15 - Q; How many stops brighter is the new planet if there are two suns instead of one?
15 - A; If there were two suns instead of two, it would be one stop brighter.

16 - Q; How many stops brighter is the new planet if there are four suns instead of two?
16 - A; If there were four suns instead of two, it would be three stops brighter.

17 - Q; What affect does a longer shutter speed have?
17 - A; Longer shutter speeds let in more light into the photo.

18 - Q; What affect does a shorter shutter speed have?
18 - A; Shorter shutter speeds let in less light into the photo.

19 - Q; What does the aperture control?
19 - A; The aperture is like the pupil, it controls exactly how large the opening is and helps to decide how much light there will be in the photograph, as well as how focused the photo can be.

20 - Q; When adjusting the aperture, how can you increase the amount of light?
20 - A; The more you open up the lens, the more light will go into the lens and make the photograph brighter.
