1. Explain the “camera obscura” effect. How is it achieved?
When a tiny hole is put in the wall of a very dark room, whatever is on the other side of the hole is projected through the light and onto the wall, upside down.
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, a dark box, and film.
4.What do modern digital cameras have in common with Niepce’s camera?
Light still passes through the lens, goes through a dark box, and exposes the film.
5. What do digital cameras use to capture an image?
Modern cameras use an electronic sensor to create digital images.
6. What is the difference between the Auto Mode and the Program mode?
Auto mode completely controls every camera option, while Program mode gives you freedom to change the flash and other options.
7. What is the Portrait mode used for? How does it work?
Portrait mode is used for pictures that have a person as the main focus. It uses the fastest aperture setting to blur out the background.
8. What is the Sports mode used for? (not just sports) How does it work?
Sports mode is used to take the clearest possible picture of something in motion. The camera uses the highest shutter speed to freeze the subject.
9. Why should you do a half press on the trigger button?
When you half press the trigger button, it gives you more control over what to focus and makes the camera respond faster.
10. What does this symbol mean? When would you use this?
The symbol means that the flash is not on; you would use it in situations where you have enough light to shoot.
11. What does this symbol mean? When would you use this?
This symbol stands for auto-flash and you would use it when you don't know whether or not you have enough light and want to leave it up to camera to figure out if it needs more light.
12. What happens to your photo if there is too much light?
The picture will be washed out.
13. What happens to your photo if there is not enough light?
The picture will be too dark.
14. What is a “stop”?
A stop is a term for how much light there is in a picture.
15. How many stops brighter is the new planet if there are two suns instead of one?
One.
16. How many stops brighter is the new planet if there are four suns instead of two?
Two.
17. What affect does a longer shutter speed of have?
A longer shutter speed gives you more light.
18. What affect does a shorter shutter speed have?
A shorter shutter speed gives you less light.
19. What does the aperture control?
The aperture controls how much light enters the camera.
20. When adjusting the aperture, how can you increase the amount of light?
By enlarging the aperture.
