1. Explain the “camera obscura” effect. How is it achieved?
Inside a 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 Newton and Huygens perfected optics and the process of making high quality 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 passes through the lens, into the camera, and exposes the film.
5. What do digital cameras use to capture an image?
The digital camera capture the images with an electronic sensor called a CCD.
"Camera Modes"
6. What is the difference between the Auto Mode and the Program mode?
Auto: The camera will completely control flash and exposure.
Program: The camera automatic-assist, just point and shoot. Sometimes you have control of flash.
7. What is the Portrait mode used for? How does it work?
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?
To freeze motion, camera will use the highest shutter speed possible.
"The Half Press"
9. Why should you do a half press on the trigger button?
Tell the camera that you're almost ready to take a shot and to be prepared. The camera will also Auto-Focus.
"Controlling Flash"
10. What does this symbol mean?
When would you use this?
This means that Flash is off, this should be used when you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.
11.What does this symbol mean?
When would you use this?
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?
The picture will be washed out.
13. What happens to your photo if there is not enough light?
The picture will be too dark.
"The Universal Stop"
14. What is a “stop.”
A relative change in the brightness of light.
15. How many stops brighter is the new planet if there are two suns instead of one?
Only 1 stop.
16. How many stops brighter is the new planet if there are four suns instead of two?
Only 2 stops.
"Shutters and Apertures"
17. What affect does a longer shutter speed of have?
The longer the shutter speed is the more light there is.
18. What affect does a shorter shutter speed have?
The shorter the shutter speed is the less light there is.
19. What does the aperture control?
The amount of light reaching the film or image sensor.
20. When adjusting the aperture, how can you increase the amount of light?
The larger the aperture opening the more light that goes in.
