"camera obscura" was an optical effect discovered by Greek and Chinese philosophers.
There is a small hole made in a completely dark room. Light is concentrated and focused through the hole so that 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?
Glass lenses.
3. What were the parts of the first modern camera invented by Niepce?
A glass lens, dark box, and film.
4.What do modern digital cameras have in common with Niepce’s camera?
4.What do modern digital cameras have in common with Niepce’s camera?
Modern cameras and Niepce's camera both produce a photo by light going 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. (CCD)
6. What is the difference between the Auto Mode and the Program mode?
Auto: the camera is in complete control of flash and exposure.
Program: you can control the flash and other camera settings.
7. What is the Portrait mode used for? How does it work?
The portrait mode is used when the camera is trying to blur the background using the setting aperture.
The portrait mode is used when the camera is trying to blur the background using the setting aperture.
8. What is the Sports mode used for? (not just sports) How does it work?
The sports mode is used to freeze motion. The camera uses the fastest shutter speed.
9. Why should you do a half press on the trigger button?
You should do a half press because the camera responds faster, there is more control over the focus, and there is a better composition.
10. What does this symbol mean? When would you use this?
This symbol means disabled flash. You use this when you do not want there to be flash at all.

10. What does this symbol mean? When would you use this?
This symbol means disabled flash. You use this when you do not want there to be flash at all.
11.What does this symbol mean? When would you use this?
This symbol means auto flash. It is used when the camera thinks that the photograph needs more light.
12. What happens to your photo if there is too much light?
If there is too much light, the picture will be too washed out.
13. What happens to your photo if there is not enough light?
If there is not enough light, the picture will be too dark.
14. What is a “stop.”
"stop" is a measurement of light. (change in the brightness of light)
15. How many stops brighter is the new planet if there are two suns instead of one?
The new planet is +1 stop.
16. How many stops brighter is the new planet if there are four suns instead of two?
The new planet is +2 stop.
17. What affect does a longer shutter speed of have?
More light.
18. What affect does a shorter shutter speed have?
Less light.
19. What does the aperture control?
The aperture controls the brightness/light.
20. When adjusting the aperture, how can you increase the amount of light?
By increasing the F-stops.
