The Camera
1. Explain the “camera obscura” effect. How is it achieved?
Inside a completely dark room, a tiny hole is created in one wall.
Through the hole light is focused, and 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?
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 Nicéphore Niépce added the final touch. He
added *film* to create the first successful photograph.
4.What do modern digital cameras have in common with Niepce’s camera?
A glass lens, a dark box, and film.
5. What do digital cameras use to capture an image?
Light passes through the lens, into the camera, and exposes the film.
Camera Modes
6. What is the difference between the Auto Mode and the Program mode?
the camera will completely control flash and exposure.
is the automatic-assist, just point and shoot.
7. What is the Portrait mode used for? How does it work?
mode is 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? (not just sports) How does it work?
mode is to freeze motion, camera will use the highest shutter speed possible.
9. Why should you do a half press on the trigger button?
- faster camera response time
- more control over focus
- encourages better composition
Controlling Flash
10. What does this symbol mean?
Disabled Flash
When would you use this?
There are many cases where you may not want flash at all.
11.What does this symbol mean?
Auto-Flash
When would you use this?
In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
Introduction to Exposure
12. What happens to your photo if there is too much light?
Too much light and the picture will be washed out.
13. What happens to your photo if there is not enough light?
Not enough light and the picture will be too dark.
Stops and Exposure
14. What is a “stop.”
The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.

Shutter and Aperture
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?
You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20. When adjusting the aperture, how can you increase the amount of light?
Larger openings
