1. Explain the “camera obscura” effect. How is it achieved?
- A tiny hole is crated in one wall. through the hole light is focused, and the outside scene is projected upside down in the opposite wall. The hole acted like a lens.
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 higher quality lenses.
3. What were the parts of the first modern camera invented by Niepce?
- Niepce added the final touch by adding film to create the first successful camera.
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?
- Instead of using plastic film, digital cameras capture the images with an electronic sensor called a CCD6. What
6. What is the difference between the Auto Mode and the Program mode?
- Auto mode will control things like flash and focus while on program mode you would have to fix this up yourself.
7. What is the Portrait mode used for? How does it work?
- To attempt to blur out the background, the camera will use the fastest lens setting.
8. What is the Sports mode used for? (not just sports) How does it work?
- To freeze motion, it takes the highest shutter speed possible.
9. Why should you do a half press on the trigger button?
- So that you can allow the camera to focus before it takes the picture.
10. What does this symbol mean?
- This symbol is the "Disabled Flash"
When would you use this?
- When you want a more dramatic shot natural light can be better.
11.What does this symbol mean?
- This means that the flash will trigger automatically.
- When you want the camera to divide wether or not flash should be used.
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.
14. What is a “stop.”
- A "stop" is used in every aspect of photography to reprint 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?
- It would be 1 stop brighter.
16. How many stops brighter is the new planet if there are four sons instead of two?
- If the new planet had 4 suns it would be 2 stops brighter.
17. What affect does a longer shutter speed of have?
- A longer shutter speed means more light.
18. What affect does a shorter shutter speed have?
- A shorter shutter speed has less light.
19. What does the aperture control?
- The aperture is like a pupil. You can control the amount of light that reaches the lens.
20. When adjusting the aperture, how can you increase the amount of light?
- set the aperture settings at a lower level.
PART II
Shutter- A device that opens and closes to expose the film in a camera.
Exposure- The amount of light that falls onto the sensor of your digital camera.
Depth of Field- The amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph
F-stop- A camera setting corresponding to a particular f-number.
Focal Length- The diastase between the center of a lens or curved mirror and its focus.
Camera parts:
Shutter button- It has two functions one is if you do a half-press to focus the photo and the other is to do a full press to take the photo.
Flash button- This button helps you set the flash on auto or that you can choose when you want to use the flash.
